Async/Await

The async and await is keywords to perform the promise-based asynchronous operation. In this article, we are going to learn how to use async/await in JavaScript.

How to use Async?

It is mandatory to define the async keyword before any function that turns your normal function to async function. Let’s start to learn it through a very basic example.

Normal Function Example

function sayHello() {
    return 'Hello World!';
}

sayHello(); // Hello World!

Copy

Async Function Example

async function sayHello() {
    return 'Hello World!';
}

sayHello(); // [object Promise] { ... }

Copy

We could explicitly return a promise with Promise.resolve() like:

async function sayHello() {
    return Promise.resolve('Hello World!');
}
async function sayHello() {
    return 'Hello World!';
}

let greeting = sayHello();
greeting.then((value) => console.log(value)); // Hello World!

Copy

or you can try this:

async function sayHello() {
    return 'Hello World!';
}

sayHello().then((value) => console.log(value) ); // Hello World!

Javascript async-await feature is used to deal with asynchronous code in javascript. The async-await is a just new technique to write async code in a sync function manner.  You can write it as a simple synchronous function. That makes it very popular and understandable. Node.js is now supporting async-await out of the box.

Async-await is a new way to write asynchronous code. Previous options for asynchronous code are  callbacks and  promises. Async/await built on top of promises. It cannot be used with plain callbacks or node callbacks.
