How do I make an HTTP request in Javascript?

You can use the XMLHttpRequest object to make HTTP requests. Here is an example of how to use it to make a GET request to a specified URL:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://example.com', true);
xhr.onload = function () {
// process the response
};
xhr.send();

Alternatively, you can use the fetch API which is more modern and easier to use. Here is an example of how to use it to make a GET request to a specified URL:

fetch('https://example.com')
.then(function(response) {
// process the response
});

You can also use the axios library, which is a popular library for making HTTP requests in JavaScript. Here is an example of how to use it to make a GET request to a specified URL:

axios.get('https://example.com')
.then(function (response) {
// handle success
console.log(response);
})
.catch(function (error) {
// handle error
console.log(error);
});

Please note that the above examples are for GET request, for other requests like POST, PUT, DELETE etc, you will need to change the method and may need to pass additional parameters.
