Sometimes, we want to create an Asynchronous function in JavaScript.

In this article, we’ll look at how to create an Asynchronous function in JavaScript.

How to create an Asynchronous function in JavaScript?

To create an Asynchronous function in JavaScript, we can use a promise.

For instance, we write

const asyncFunct = new Promise((resolve, reject) => {
  //...
  resolve();
});

to create the asyncFunct promise with the Promise constructor.

We call Promise with a callback that calls resolve when our async code is finished.

Then we use await asyncFunct; to wait for the promise to finish before we run the code below it.

Conclusion

To create an Asynchronous function in JavaScript, we can use a promise.
