Benchmark: Native XHR vs jQuery Ajax3

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Script Preparation code:

function showResult(data) {
    console.log(data);
}
var newUrl = "https://www.googleapis.com/discovery/v1/apis";

Tests:

Native XHR
var xhr = new XMLHttpRequest(); xhr.open("GET", newUrl, true); xhr.onreadystatechange = function() { if (xhr.readyState === 4) { showResult(xhr); } } xhr.send();
Native XHR 2
var xhr = new XMLHttpRequest(); xhr.onload = showResult; xhr.open("GET", newUrl, true); xhr.send();
Native fetch.then
var request = fetch(newUrl).then(showResult);
jQuery Ajax
var request = $.ajax({ type: "GET", url: newUrl, success: showResult, data: null });
jQuery Ajax (Async)
var request = $.ajax({ type: "GET", async: true, url: newUrl, success: showResult, data: null });
jQuery Get
var request = $.get(newUrl, showResult);
jQuery Get 2
var request = $.get(newUrl).done(showResult);
jQuery getJSON
$.getJSON(newUrl, null, showResult);

Let's break down the provided benchmark and explain what's being tested, compared options, pros and cons of each approach, library usage, special JS features or syntax (if any), and other considerations.

**Benchmark Overview**

The benchmark tests four different ways to make an HTTP request in JavaScript:

1. Native XHR
2. Native XHR 2 (a variation of the previous one)
3. Native fetch.then (using the Fetch API)
4. jQuery Ajax (and its variations)

Each test case is executed multiple times, and the results are displayed in terms of executions per second.

**Tested Options**

Here's a comparison of the different options:

* **Native XHR**: This is the original XMLHttpRequest API used for making HTTP requests.
	+ Pros: native, widely supported, simple to use.
	+ Cons: older, less efficient than other options.
* **Native XHR 2**: A variation of Native XHR that uses a more modern approach with the `onreadystatechange` event instead of the `onload` event.
	+ Pros: slightly faster and more efficient than Native XHR.
	+ Cons: still an older API, less supported than other options.
* **Native fetch.then**: This is a newer API introduced in modern browsers that allows for making HTTP requests with a simpler syntax.
	+ Pros: fast, modern, widely supported.
	+ Cons: requires a more modern browser to work, not as widely used as XMLHttpRequest.
* **jQuery Ajax**: A library-based approach to making HTTP requests using jQuery.
	+ Pros: easy to use, widely supported, simple to set up.
	+ Cons: adds extra overhead due to the library, may impact performance.

**Library Usage**

The benchmark uses jQuery for its `Ajax` functions. This is done to compare the performance of jQuery's implementation with native HTTP requests.

**Special JS Features or Syntax (if any)**

This benchmark does not use any special JavaScript features or syntax beyond what's required for making HTTP requests.

**Other Considerations**

* **Browser support**: The benchmark uses Chrome 69 as the test browser, which is a relatively modern browser. This means that older browsers may not be supported by the benchmark.
* **Environment**: The benchmark runs in a controlled environment with no external factors influencing the results (e.g., network conditions, device hardware).

**Alternatives**

Other alternatives to these options include:

* **Axios**: A popular alternative to XMLHttpRequest and jQuery Ajax for making HTTP requests.
* **Fetch API with async/await**: A newer approach to making HTTP requests using the Fetch API that uses async/await syntax.

Overall, this benchmark provides a good comparison of four different approaches to making HTTP requests in JavaScript, highlighting the pros and cons of each option.
