How do I make an HTTP request in Javascript?

 

To make an HTTP request in JavaScript, you can use the built-in XMLHttpRequest object or the more modern fetch API.

Here's an example of making a GET request using XMLHttpRequest:

javascript

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onreadystatechange = function() {
  if (xhr.readyState === XMLHttpRequest.DONE) {
    if (xhr.status === 200) {
      console.log(xhr.responseText);
    } else {
      console.error(xhr.statusText);
    }
  }
};
xhr.send();

And here's an example of making a GET request using the fetch API:

javascript

fetch('https://api.example.com/data')
  .then(response => {
    if (!response.ok) {
      throw new Error(response.statusText);
    }
    return response.json();
  })
  .then(data => console.log(data))
  .catch(error => console.error(error));
