Understanding Javascript 'async' & 'await' with an Example

// defining the async function which waits for the promise to be resolved / rejected
const getName = async () => {
    try {
        let name = await namePromise;
        console.log(`Name received from DB = ${name}`);
    } catch (err) {
        console.log(err);
    }
}

// defining the promise object with the producer
let namePromise = new Promise((resolve, reject) => {
    console.log("Getting name from DB...");
    setTimeout(() => {
        resolve("Srishti");
    }, 3000);
});

getName();

Getting name from DB...
Name received from DB = Srishti

// defining the async function which waits for the promise to be resolved / rejected
const getName = async () => {
    try {
        let name = await namePromise;
        console.log(`Name received from DB = ${name}`);
    } catch (err) {
        console.log(err);
    }
}

// defining the promise object with the producer
let namePromise = new Promise((resolve, reject) => {
    console.log("Getting name from DB...");
    setTimeout(() => {
        reject(new Error("Error getting name!"));
    }, 3000);
});

getName();

Getting name from DB...
Error: Error getting name!
