Async simply allows us to write promises-based code as if it was synchronous and it checks that we are not breaking the execution thread.
Async functions will always return a value. It makes sure that a promise is returned and if it is not returned then JavaScript automatically wraps it in a promise which is resolved with its value.
Example 1: In this example, we will see the basic use of async in JavaScript.
const getData = async () => {
let data = "Hello World";
return data;
}
getData().then(data => console.log(data));
