Promises: Objects that represent the eventual completion (or failure) of an asynchronous operation.
Async/Await: Syntax that makes asynchronous code easier to read and write.

7.2 AJAX (Asynchronous JavaScript and XML)

AJAX allows you to send and receive data from a server without reloading the page.

How AJAX Works:

Create an XMLHttpRequest object.
Open a connection to the server using the open() method.
Send the request using the send() method.
Handle the response using the onload event.

Example:

const xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data');
xhr.onload = function() {
  if (xhr.status === 200) {
    console.log(xhr.responseText);
  } else {
    console.error('Request failed');
  }
};
xhr.send();

7.3 Fetch API

The Fetch API provides a more modern and flexible way to make network requests.

Example:

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Request failed', error));
