Asynchronous Programming with Callbacks and Promises in Java Script

  Asynchronous Programming with Callbacks and Promises in Java Script

Asynchronous programming is a programming paradigm that allows you to execute multiple tasks simultaneously, without blocking the main thread. In JavaScript, asynchronous programming is typically done using callbacks or promises.

Here's an example of a callback function that is executed after a delay:

javascript

function myCallback() {

  console.log("Callback executed.");

}

setTimeout(myCallback, 1000);

And here's an example of a promise that is resolved after a delay:

javascript

function myPromise() {

  return new Promise(function(resolve, reject) {

    setTimeout(function() {

      resolve("Promise resolved.");

    }, 1000);

  });

}

myPromise().then(function(result) {

  console.log(result);

});
