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.
