Benchmark: Comparison Ajax, Fecth and XHR

HTML Preparation code:

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

Tests:

Xhr
const xhr = new XMLHttpRequest(); xhr.open('GET', 'https://www.googleapis.com/discovery/v1/apis'); xhr.onload = () => console.log(JSON.parse(xhr.responseText)); xhr.send();
Fetch
fetch('https://www.googleapis.com/discovery/v1/apis').then(response => response.json()).then(console.log)
Ajax
$.ajax({ url: 'https://www.googleapis.com/discovery/v1/apis', type: 'GET', dataType: 'json', async: false, }) .done(function(res) { console.log(res) })

Let's break down the provided benchmark and explain what is being tested, compared, and their pros and cons.

**What is being tested?**

The benchmark measures the performance of three different approaches to make an HTTP request in JavaScript: XMLHttpRequest (XHR), fetch(), and jQuery's $.ajax() method. The tests are designed to compare the execution speed and efficiency of these methods.

**Options compared:**

1. **XMLHttpRequest (XHR)**: This is a native JavaScript API for making asynchronous HTTP requests.
2. **fetch()**: This is a modern, promise-based API introduced in ECMAScript 2015 (ES6) for making HTTP requests.
3. **jQuery's $.ajax() method**: This is a popular library function for making AJAX requests.

**Pros and Cons of each approach:**

1. **XMLHttpRequest (XHR)**:
	* Pros:
		+ Native JavaScript API, no additional libraries needed.
		+ Can be used in older browsers that don't support fetch().
		+ Provides more fine-grained control over the request.
	* Cons:
		+ Requires more code to set up and handle the request (e.g., opening the request, setting headers, handling errors).
2. **fetch()**:
	* Pros:
		+ Modern, promise-based API makes it easy to handle asynchronous requests.
		+ No additional libraries needed, as it's built into modern browsers.
		+ Provides a simpler syntax for making HTTP requests.
	* Cons:
		+ Requires a modern browser that supports the fetch() API (older browsers may not support it).
3. **jQuery's $.ajax() method**:
	* Pros:
		+ Provides a simplified syntax for making AJAX requests, which can be easier to read and maintain.
		+ Works in older browsers that don't support the native fetch() or XHR APIs.
	* Cons:
		+ Adds an additional library dependency (jQuery), which may not be desirable for smaller projects.

**Library usage:**

The benchmark uses jQuery's $.ajax() method, as indicated by the "Html Preparation Code" containing a reference to the jQuery library. The library is used to simplify the syntax and provide a more familiar API for making AJAX requests.

**Special JS feature or syntax:**

None of the provided test cases use any special JavaScript features or syntax that are not commonly known or used in everyday development. However, it's worth noting that the fetch() API relies on the modern ECMAScript standard, which may require some developers to update their knowledge and skills.

**Other alternatives:**

For making HTTP requests in JavaScript, other alternatives exist, such as:

1. **ActiveXHttpRequest**: An older API for making asynchronous HTTP requests, primarily used in Internet Explorer.
2. **XMLHttpRequest2**: A modern API for making asynchronous HTTP requests, which provides some additional features and improvements over the traditional XHR API.
3. **Axios**: A popular third-party library for making HTTP requests in JavaScript, providing a simpler and more robust API than jQuery's $.ajax() method.

These alternatives may be worth exploring depending on the specific requirements and constraints of your project.
