What You Will Learn
introduction to reactjs
Get introduced to React.js, a popular JavaScript library for building user interfaces. Learn its history, advantages, environment, and its role in creating single-page applications.
Topics Covered:
- Virtual DOM – A lightweight copy of the actual DOM that enhances performance by updating only the necessary components.
- ECMAScript – A standardized scripting language that adds modern JavaScript features, making development efficient.
- Bundling – The process of combining multiple JavaScript files into one, improving application performance.
- Minification – Reducing the size of JavaScript files by removing unnecessary characters, and improving load times.
- ESLint – A tool that helps maintain code quality and consistency by identifying errors and enforcing coding standards.
- Single-Page Application (SPA) – A web app that dynamically updates content without reloading the page, enhancing user experience.
- Multi-Page Applications (MPA) – Traditional web applications where each page request loads a new HTML file from the server.
react concepts - part 1
Learn how to set up your environment to run a React application and structure your codebase to create a Phone Directory application.
Topics Covered:
- JSX – A syntax extension for JavaScript that allows writing HTML-like code within JavaScript.
- Differences between JSX and HTML – JSX is similar to HTML but follows JavaScript rules, such as using className instead of class.
- React.createElement() method – A method used to create elements in React without using JSX.
- Rendering elements into DOM – The process of displaying React elements on the web page using the ReactDOM library.
- Components – Reusable building blocks in React that help create modular and maintainable applications.
- Styling components and elements – Various methods for styling React components, including inline styles, CSS modules, and styled components.
- Rendering content dynamically – Using JavaScript expressions within JSX to update UI elements based on state and props.
react concepts - part 2
Build on the concepts learned in the previous module and solidify your understanding of React.
Topics Covered:
- Props – Short for properties, props allow data to be passed between React components.
- Event handling – Managing user interactions, such as clicks and form submissions, using React event handlers.
- State – An object in a component that stores dynamic data and determines how the component behaves.
- Component Lifecycle – The different phases a React component goes through, from creation to updates and unmounting.
- Smart vs Dumb Components – Smart (stateful) components manage state, while dumb (stateless) components focus only on UI.
- Routing – Handling navigation in a React application using React Router to create seamless user experiences.
