Why learn to code?  What’s the benefit of coding? Today, we’ll answer all such questions in this detailed article. We’ll unravel the top reasons why learning to code is a crucial 21st-century skill and how you can start your coding journey! Top Reasons To Learn To Code  There are many advantages to learning to code. Let’s discuss the top reasons. 1. You Can Work From Home The COVID-19 pandemic has changed how companies operate. Organisations worldwide adopted ‘work from home’ technologies and methods to help them function in these uncertain times. According to a Gartner survey, 80% of companies plan to allow employees to work remotely at least part-time after the pandemic ends. This means that even after the virus is gone, the work culture would remain changed. Working from home is very beneficial in some areas. First, you don’t have to face the commute and can easily save a ton of time. Second, you can work more comfortably and create your schedules. When you learn to code and become a technical professional, you can bag roles that offer remote work. In non-technical functions such as sales and management, your chances of getting remote work are much less than technical roles such as frontend developer or software engineer.  2. You will Develop Analytical Skills As you learn to code, you will develop logical thinking and analytical skills. Analytical skills are vital for any role as they help you solve problems quickly and advance your career. These skills will benefit you everywhere, from securing a job interview to facing a role’s day-to-day issues. Here’s how analytical skills will help nurture your: Critical thinking skills Critical thinking refers to the ability to evaluate a problem with a careful thought process. With this ability, you can break down issues or arguments into steps and assess them independently.  Problem-Solving Skills Problem-solving skills help you find solutions to upcoming and existing issues. Effective problem-solving skills will prepare you to face any work challenges, making you a valuable asset to your company.  Decision-Making Skills As you’ll learn to code, you’ll enhance your decision-making skills to select a course of action or object from multiple alternatives. Coding helps you become more efficient in analysing different strategies and choose the right course of action for a particular situation.  3. You can Get High-Paying Jobs Why learn to code?

HashMap is a collection class in Java. You can use it to store key and value pairs. Its performance depends on the initial capacity and the load factor. HashMap has various methods that allow you to use its hash table data structure.  In the following article, we’ll explore what HashMap is and learn about its various constructors through examples.  What is HashMap? HashMap is a collection class based on Map. We use it to store Key & value pairs. You denote a HashMap Java as HashMap<K, V>, where K stands for Key and V stands for Value.  HashMap is similar to the Hashtable class. The difference between the two is that HashMap is unsynchronized while Hashtable isn’t. Also, unlike Hashtable, HashMap allows null values and the null key.  Since HashMap isn’t an ordered collection, it doesn’t return the keys and values in the order you insert them. Also, HashMap doesn’t sort the stored keys and values. If you want to use the HashMap class and its methods, you’ll have to import java.util.HashMap (or its superclass). HashMap gives you a simple implementation of Java’s Map interface. You can access the key-value pairs you store through HashMap by using an index of another type (such as an integer). Keep in mind that if you use a duplicate key, it replaces the element of the relevant key. Also, you can only use one null key object; however, there can be any number of null values.  HashMap implements Cloneable, Serializable, Map<K, V> interfaces. It extends the AbstractMap<K, V> class, and its direct subclasses are PrinterStateReasons and LinkedHashMap.  Features of HashMap  Following are the primary features in HashMap:  It is a component of the java.util.package. You can use duplicate values, but HashMap doesn’t allow duplicate keys. It means one key can’t have multiple values, but multiple keys can have a single value.  You can use null keys only once, but you can use various null values.  HashMap provides no guarantees regarding the map’s order. So, it doesn’t guarantee if the order will remain constant.  HashMap is very similar to Hashtable, with the only difference being that HashMap is unsynchronized.  HashMap implements a Serializable and Cloneable interface.  HashMap Constructors There are four constructors in HashMap: 1. HashMap() HashMap() is the default constructor that creates an instance with a load factor of 0.75 and an initial capacity of 16. Example:  // Showing how HashMap() constructor works  import java.io.*; import java.util.*; class AddElementsToHashMap {     public static void main(String args[])     {         // You don’t have to mention the         // Generic type twice         HashMap<Integer, String> hm1 = new HashMap<>();         // Using Generics to initialize HashMap         HashMap<Integer, String> hm2             = new HashMap<Integer, String>();         // Use the put method to add any element         hm1.put(1, “A”);         hm1.put(2, “B”);         hm1.put(3, “C”);         hm2.put(4, “D”);         hm2.put(5, “E”);         hm2.put(6, “F”);         System.out.println(“Results of hm1 are : “                            + hm1);         System.out.println(“Results of HashMap hm2 are : “                            + hm2);     } } Output:  Results of hm1 are : {1=A, 2=B, 3=C} Results of hm2 are : {4=D, 5=E, 6=F} 2. HashMap(int initialCapacity)   HashMap(int initialCapacity) would create an instance with load 0.75 and a specific initial capacity.    Example:   // Showing how HashMap(int initialCapacity) constructor works     import java.io.*; import java.util.*; class AddElementsToHashMap {     public static void main(String args[])     {         // You don’t have to mention the         // Generic type twice         HashMap<Integer, String> hm1 = new HashMap<>(10);         // Using Generics to initialize HashMap         HashMap<Integer, String> hm2             = new HashMap<Integer, String>(2);         // Use the put method to add any element         hm1.put(1, “A”);         hm1.put(2, “B”);         hm1.put(3, “C”);         hm2.put(4, “D”);         hm2.put(5, “E”);         hm2.put(6, “F”);         System.out.println(“Results of hm1 are : “                            + hm1);         System.out.println(“Results of HashMap hm2 are : “                            + hm2);     } } Output:  Results of hm1 are : {1=A, 2=B, 3=C} Results of hm2 are : {4=D, 5=E, 6=F} 3. HashMap(int initialCapacity, float loadFactor)  HashMap(int initialCapacity, float loadFactor) generates an instance with a specific load factor and initial capacity. Example: // Showing how  HashMap(int initialCapacity, float loadFactor) Constructor works import java.io.*; import java.util.*; class AddElementsToHashMap {     public static void main(String args[])     {         // You don’t have to mention the         // Generic type twice         HashMap<Integer, String> hm1             = new HashMap<>(5, 0.75f);         // Using Generics to initialize the HashMap         HashMap<Integer, String> hm2             = new HashMap<Integer, String>(3, 0.5f);         // Use the put method to add elements         hm1.put(1, “A”);         hm1.put(2, “B”);         hm1.put(3, “C”);         hm2.put(4, “D”);         hm2.put(5, “E”);         hm2.put(6, “F”);         System.out.println(“Results of hm1 are : “                            + hm1);         System.out.println(“Results of HashMap hm2 are : “                            + hm2);     } } Output:  Results of hm1 are : {1=A, 2=B, 3=C} Results of hm2 are : {4=D, 5=E, 6=F} 4. HashMap(Map map) HashMap(Map map) would create an instance with the same mappings as the map you specify.  Example: // Showing how HashMap(Map map) constructor works  import java.io.*; import java.util.*; class AddElementsToHashMap {     public static void main(String args[])     {         // You don’t have to mention the         // Generic type twice         Map<Integer, String> hm1 = new HashMap<>();          // Using Generics to initialize HashMap         HashMap<Integer, String> hm2             = new HashMap<Integer, String>(hml);         // Use the put method to add any element         hm1.put(1, “A”);         hm1.put(2, “B”);         hm1.put(3, “C”);         hm2.put(4, “D”);         hm2.put(5, “E”);         hm2.put(6, “F”);         System.out.println(“Results of hm1 are : “                            + hm1);         System.out.println(“Results of HashMap hm2 are : “                            + hm2);     } } Output:  Results of hm1 are : {1=A, 2=B, 3=C} Results of hm2 are : {4=D, 5=E, 6=F} Learn more about Java Java has many classes apart from HashMap. Learning about the nitty-gritty of each of those classes, their uses, and integration in Java by yourself is pretty challenging. The best way to go about this process is by taking a computer science course. Taking a professional course will enable you to master the necessary skills and concepts through a structured curriculum. Furthermore, such courses offer an immersive learning experience facilitated by videos, live sessions, and online lectures that make it easier for you to understand theoretical fundamentals.

What is React? React is an open-source, component-based JavaScript library used to create quick and interactive interfaces or UI components for users for web and mobile-based applications.   Ever since its release in 2013 by Facebook, React, a JavaScript library used to build web applications, has consistently witnessed an upward trend. It is now the most-used JavaScript library alongside the likes of jQuery, Vue, and Angular. It is a declarative and highly accurate library that provides reusable code, which enhances the efficiency and flexibility of single-page applications.  Its key features are SX and Virtual DOM, which set it apart from other JavaScript libraries. Popular companies like Facebook, TripAdvisor, and Airbnb are users of React. Key Highlights of React The component-based, front-end library optimizes the page loading speed and efficiency of single-page applications. React helps in generating easy-to-use interactive UIs. It is used to design comfortable and interactive views for every state in the application. It offers on-time updates that help users to receive relevant components required when data changes. React breaks the UI into smaller individual components, enabling users to simultaneously work on each component resulting in faster app development. Why does React have the edge over other frameworks? React has a lot of efficient features that make the library stand out against other libraries. The following is the list of powerful features that have catapulted React to the numero uno position: Effective DOM Manipulation DOM (Document Object Model) is a crucial part of the web application, as it represents the web page of a document, generally HTML. DOM manipulation has become the latest trend in modern applications as they require numerous animations, state transitions, impactful effects, and so on:  The Virtual DOM is a virtual model of the actual DOM tree with each branch ending in a node that contains objects. The feature enables the users to update only the necessary parts of the DOM tree instead of re-rendering the entire UI. The whole process of implementing a virtual DOM is faster as it stays only in the memory without providing access to the user. JSX The JavaScript’s syntax extension is merged with React to clearly define how the user interface (UI) is supposed to look. JSX can be used to write HTML structures in a file that has JavaScript code. By doing this, the code becomes easily understandable as the process avoids complex JavaScript DOM structures. More functionality with lesser code React facilitates the simple and quick generation of dynamic web applications as it requires less coding against JavaScript that involves complex coding. Quick application development Components are the foundation of any React application. Most apps require a lot of components to control each task in app development. React components have a wide range of logic and controls that can be reused because of which the applications can be developed at a quick pace. Easy error debugging In React, the child components are placed inside the parent components, and so the data flows only in one way. The single direction of data enables the app developers to identify the exact location of the error in an application resulting in faster debugging. React components are designed based on the Separation of concerns principle, according to which a computer program is separated into smaller sections, each of which addresses different issues. Use of UI component library A set of ready-made components that provide the necessary blocks of code for developing apps constitute the UI component library. The use of the UI library, Kendo React, brings in a lot of advantages like greater compatibility, better accessibility, speed, and easier handling. For instance, the Create React app is used at the beginning stage of React app setup. This enables the developers to start using the React app with a single command.  Redux Redux is a popular state management library used in React. It places all the data inside a store such that each component has access to the store. The two powerful concepts of Redux are actions and reducers.  Actions are the events that transfer the data, and reducers are functions that perform a task corresponding to the data and return it to a new state. Easy to learn It is easy to learn React as it is an amalgamation of HTML and JavaScript concepts with some add-ons. Use in developing mobile apps  React is known for its effectiveness in web application development but is not limited to only that. React Native, an immensely popular framework of React helps in developing mobile applications.  Chrome extension to debug React applications Facebook has come up with a chrome extension that is exclusively used for debugging React applications. This makes debugging simpler and faster. The above features make React one of the most-used JavaScript libraries, which are preferred by a huge number of businesses over the likes of jQuery, Vue, and Angular.  In addition to this, React does not insist on strict code conventions or file organizations, unlike other frameworks. This helps developers to have their convenient conventions and use React in any way they like. React can be assigned to handle a single button, a few interface pieces, or an application’s entire user interface.  Prerequisites for learning and using React The following list will help developers who have just started using React determine if they are ready to take the plunge: A basic understanding of HTML, JavaScript, CSS, Babel, and Package manager: Front-end developers should know how to generate CSS selectors, HTML tags and to develop applications using HTML and CSS. A good grip on ES6, JSX, and their features: In React, the developers need to use JSX that gives the flavour of HTML JavaScript. A complete understanding of how to use JSX is mandatory to learn React. Understanding of how Node Package Manager (NPM) works: A basic understanding of installing packages using NPM, finding required software from the NPM registry is indispensable for developing React apps.  React Vs. Angular and Vue Angular, developed by Google in 2010, is a TypeScript based framework. Two versions of the same were released in 2016 (Angular 2) and 2020 (Angular 11). Vue, a.k.a Vue.js, was released by Evan You in 2014. The latest version of Vue was released in September 2010 (Vue 3.0), which has its own GitHub tool.  Let us compare the key aspects of the three frameworks.  Key features React Angular Vue Year of release 2013 2010 2014 Website Reactjs.org Angular.io vuejs.org Latest Version 17.x 11 3.0.x Leading companies using the framework Facebook, Uber Google, Wix Alibaba, GitLab Number of Contributors 1533 1352 382 Number of jobs in LinkedIn 70963 72747 11590 Future Scope of React in the Industry With growing patronage from new-age developers, React has become a top trend in the front-end development industry.  React developers are better compensated than other web developing frameworks. According to PayScale, the average salary offered to developers in React.js is $92,341 per year. Compensations increase as you level up in your career — L4 Lead Front End Engineers are paid a high base salary of $115,862 per year. It is widely preferred by many companies owing to its simplicity and quick pace and so React developers have a huge demand in the market. Many leading companies like Facebook, PayPal, Instagram, UBER, and Airbnb use React for their web development. Therefore, React developers have a potential future as the technology is used in a wide range of industries. Ever since its release in 2013, React has been consistently growing in demand and popularity and Facebook adding many advanced features to the tool is making it more desirable and stronger in the market. ReactJs has completely revamped the front-end handling making it faster and easier by addressing its view issue and providing a UI view and storage layer. Let us look at the key parameters of React that show its current trend in the market: Key Parameters Figures of React Number of Watchers 6,700 Number of Stars 16,400 Number of Forks 32,900 Number of Contributors 1,533 React is also comparatively easier to learn and has a wider community than other libraries like Angular or Vue. The job market for React developers looks very promising.  The following table shows the number of positions available for React developers: List of job portals Number of Vacancies LinkedIn 70963 Indeed 14595 Simply Hired 10508 Dice 3529 AngelList 4383 Hired 9 Remote 1136 To Conclude The path to learning React might take time, but it is certainly worth the effort and time given its popularity as the most-used JavaScript for developing modern applications. The powerful and efficient features of React and the ease of handling them make it unique from other libraries and frameworks. The tools introduced by React like JSX, DOM, and reusable components have completely revolutionized and simplified the process of app development.  All the above features make ReactJs an indispensable tool in web development. Developers who look beyond Angular and Vue find React as their one-stop destination. According to The State of JavaScript 2020 survey, React tops the list of most-used JavaScript libraries, which proves that this framework is here to stay for a long time.

The United States has the largest number of software developers specializing in technologies like Python. If you want to be one of them, it is best to start with the fundamentals. We have compiled a Python cheat sheet below to kickstart your learning journey! Applications of Python As a leading general-purpose programming language, Python is used for a wide range of industry applications.  Here are some of its popular use cases: Web development is backed by frameworks like Django, Pyramid, Flask, and content management systems such as Plone. Scientific and numeric computing powered by SciPy, Pandas, IPython, etc. Desktop GUIs enabled by toolkits like Livy, wxWidgets, PySide, and GTK+. Software development, including build, control and management, and testing. Programming-related education and training, both at the introductory and advanced levels. Business applications encompassing ERP and e-commerce solutions. Examples of enterprise application platforms include Odoo and Tryton.  In terms of technical skills, Python lets you master two coding tasks at once, i.e., server-side development and machine learning. It is open-sourced, equipped with extensive libraries, and supports user-friendly data structures. Moreover, you can easily find a Python cheat sheet pdf online to clarify the basics.  The following Python cheat sheet will familiarize you with the data types, math operators, strings, functions, lists, and tuples. We have also included Regular Expressions (Regex) information to give you a well-rounded view of the programming language.  Getting Started with Python The first step is to check whether your computer has pre-installed Python. You can do so via the Command Line search. After that, you can begin writing your code in any text editor and save the file in .py format. You would then be able to run the code in the Command Line prompt.  However, this approach is suitable only for straightforward, non-data science tasks. You might want to switch to IDE or IDLE if you want to interpret your code. If you are a beginner in python and data science, upGrad’s data science online courses can definitely help you dive deeper into the world of data and analytics. IDLE stands for Integrated Development and Learning Environment. Every installation comes with a Python IDLE that highlights relevant keywords or string functions. Shell is the default mode of operation that lets you test various code snippets via the following tasks:  Read statements Evaluate results Print results on the screen Loop to the next statement  Data Types in Python A Python value is termed an “object.” Every object has a particular data type. Here is a list of the most-used data types with examples: Integers: Represented by keyword (int), it includes integer numbers, such as -2, -1, 0, 1, 2, etc. Floating-point numbers: Non-integer fractional numbers denoted by (float). For example, -1.5, -1, -0.5, 0, 0.5, 1, 1.5 Strings: Sequence of characters that cannot be changed once defined. For example, “hello”, “hey”. Typically, single, double, or triple quotes are used to create a basic Python string.  Whichever option you choose, keep it consistent throughout the program. Here are some other things to keep in mind: The print() function would output your string to the console window.  You can apply join() or replace() to modify these strings but cannot rewrite the original.  Lists: Ordered sequence of elements that keep the data together so that you can perform operations on several values at once. Each value is termed as an “item” and placed within square brackets. The items can be changed once stored. Consider the examples below. one_list = [1, 2, 3, 4] two_list = [“b”, “c”, “f” “g”] three_list = [“4”, d, “car”, 7] Tuples: Similar to lists, but the stored values cannot be changed. You can create a tuple as follows: new_tuple = (5, 6, 7, 8) my_tuple[0:5] (2, 3, 4) Dictionaries: Indexes that hold key-value pairs. It can include integers, boolean, or strings. For instance, Buyer 1= {‘username’: ‘john doe, ‘online’: true ‘friends’:150}  You can use the any of these two options to create a dictionary: my_dict = {} new_dict= dict()  Let us now look at the common practicalities of these data types.  String Concatenation & Replication Concatenation involves adding two strings together with the “+” operator, as demonstrated below. my_string = “I love” other_string = “reading books” final_string = my_string + other_string Notably, concatenation is only possible for the same data types. If you try to use “+” for a string and integer, you will encounter an error in Python.  The replication command lets you repeat a string using the * operator.  ‘Alex’ * 4 ‘AlexAlexAlexAlex’ print(“Alex” * 4) However, this only holds true for string data types. When * is applied to numbers, it acts as a multiplier, not a replicator. Math Operators You can apply several math operations with numbers via specific operators. For reference, let’s examine this list: To return an exponent, use “**” (2 ** 4 = 16) To multiply numbers, use the single asterisk sign, “*” (2 * 2 = 4) To get the quotient in integer division, use “//” as the operator (20 // 8 = 2)  For the remainder, apply the “%” symbol (20 % 8 = 4) For the floating point number, apply “/” (20 / 8 = 2.5) For subtraction, “-” is the standard operator (6 -2 = 4) To add numbers, use “+” (3 + 3 = 6) Functions in Python Functions are blocks of coded instruction capable of performing particular actions. Python has some built-in functions, namely:  Input(): Prompts the user for input, which is further stored as a string.  len(): Finds the length of strings, lists, tuples, dictionaries, and other data types. filter(): Excludes items in iterable objects, such as lists, tuples, or dictionaries.  You can also define your own function using the def keyword followed by name():. Here, the parentheses can either stay empty or contain any parameters to specify the purpose of the function.  Performing Operations with Lists  The list() function provides an alternate way of creating lists in Python. The statements mentioned below illustrate this option.  my_list = list ((“1”, “2”, “3”)) print(my_list) The append() or insert() functions are used to add new items to a list. Functions like remove() and pop() let you remove items from a list. Alternatively, you may try the del keyword to delete a specific item. The “+” operator combines two lists, and the sort () function organizes the items in your list.  Working with ‘If Statements’ Python supports the basic logical conditions from math:   Equals: a == b Not Equals: a != b Less than: a < b Less than or equal to a <= b Greater than: a > b  Greater than or equal to a >= b  You can leverage these conditions in various ways. But most likely, you’ll use them in “if statements” and loop. The goal of a conditional statement is to check if it’s True or False. if 5 > 1: print(“That’s True!”) Output: That’s True! You can know more about Nested If Statements, Elif statements, If Else Statements, and If-Not statements in any Python cheat sheet pdf.  Creating Python Classes Every element, along with its methods and properties, is an object in Python, considering it is an object-oriented programming language. Classes are blueprints for creating these objects. While a class is manifested in a program, objects are the instances of the class. Suppose you have to create a SampleClass with a property named x. You will begin with: class SampleClass:  z = 4 In the next step, you will create an object using your SampleClass. You can do so using p1 = SampleClass(). You can further assign attributes and methods to your object with a few simple steps.  Python Exceptions (Errors) Here is a list of some common errors that pop up while using Python.  KeyError: When a dictionary key doesn’t feature in the set of existing keys. TypeError: When an operation or function is inapplicable to an object type. ValueError: When a built-in operation or function gets an argument with the correct type but of inappropriate value.  IndexError: When a subscript cannot be detected, being out of range.  ZeroDivision: When the second argument of a division operation is zero. AttributeError: When an attribute assignment fails. ImportError: When an import statement fizzles in locating the module definition. OSError: A system-related error. For troubleshooting these errors in Python, you can use exception-handling resources — try/except statements.  Python Regex Cheat Sheet Regex is an integral part of any programming language. It helps you search and replace specific text patterns. In other words, it is a set of characters that lets you remember syntax and how to form patterns depending on your requirements. So, let’s look at some useful regex resources for Python.  Basic characters ^ matches a string expression to its right before the line break $ matches the expression to its left before the string experiences a line break xy matches the xy string. a|b matches the a or b expressions. b is left untried if a gets matched first.  Quantifiers + matches an expression to its left once or more than once. * matches an expression to its left 0 or multiple times. ? matches an expression to its left between 0 and 1 time.  {p} matches an expression to its left not less than p times. {p,q} matches an expression to its left between p and q times.  {p,} matches an expression to its left p times or more than p times.  {,q} matches an expression to its left through q times.  Module Functions re.findall (A, B) returns a list of all instances of expression A in the B string.  re.search (A, B) returns a re-match object of the first insurance of expression A in the B string.  re.sub (A, B, C) replaces A with B in the C string.  You can find more regular expressions on character classes, sets, and groups in any Python regex cheat sheet available online.  Summing up In this blog, we detailed the foundational steps of working with the Python programming language. We covered everything from IDLE to integers, strings, lists, dictionaries, tuples, and math operators. We also learned how to define a function and discussed examples of different statements and errors. By no means is the above checklist complete, but it can definitely help you get the hang of Python. Once you are through with these nuts and bolts, you can increase your speed and productivity with regular practice.  Additionally, Python’s active support community and advanced online courses can help you stay updated.
