Benchmark: fetch vs ajax call Version 2

HTML Preparation code:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

Script Preparation code:

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

Tests:

Ajax
var request = $.ajax({ type: "GET", url: newUrl, success: showResult, data: null });
Fetch
fetch(newUrl) .then( function(response) { response.json().then(function(data) { showResult(data); }); } ) .catch(function(err) { console.log('Fetch Error :-S', err); });

Let's break down the provided benchmark and explain what is being tested, compared, and other considerations.

**Benchmark Overview**

The provided JSON represents two test cases: `Ajax` and `Fetch`. Both tests aim to compare the performance of JavaScript libraries (jQuery and Fetch) for making asynchronous HTTP requests.

**Script Preparation Code**

In both test cases, a function `showResult(data)` is defined to log the received data to the console. Additionally, a URL `newUrl` is defined as the base for the request.

**Html Preparation Code**

The `Html Preparation Code` includes a reference to jQuery library version 3.6.0, which is used in the `Ajax` test case.

**Test Cases**

### Ajax

* **Benchmark Definition**: The `Ajax` test case uses jQuery's `ajax()` method to make a GET request to `newUrl`. The response is logged to the console using the `showResult()` function.
* **Library**: jQuery (version 3.6.0)
* **Purpose**: jQuery provides an easy-to-use API for making HTTP requests, which can simplify web development.

Pros:
	+ Easy to use and integrate with other jQuery features
	+ Supports various request methods and headers

Cons:
	+ Adds extra overhead due to the library's complexity
	+ May have slower performance compared to native JavaScript implementations

### Fetch

* **Benchmark Definition**: The `Fetch` test case uses the built-in `fetch()` API to make a GET request to `newUrl`. The response is logged to the console using the `showResult()` function.
* **Library**: None (native JavaScript implementation)
* **Purpose**: The Fetch API provides a modern, lightweight way to make HTTP requests.

Pros:
	+ Fast and efficient
	+ Easy to use and integrate with native JavaScript

Cons:
	+ Requires modern browsers that support the Fetch API
	+ May have limited browser support compared to jQuery

**Comparison**

The benchmark compares the performance of `Ajax` (using jQuery) and `Fetch` (native JavaScript implementation) for making GET requests. The test measures the number of executions per second, which indicates the speed of the request processing.

**Special Features/ Syntax**

* None mentioned in this explanation.

**Other Alternatives**

If you need alternative libraries or APIs for making HTTP requests, consider:

1. Axios: A popular promise-based library for making HTTP requests.
2. Request: A lightweight library that provides a simple way to make HTTP requests.
3. Native Web API alternatives:
	+ XmlHttpRequest (older browsers)
	+ ActiveXObject (older IE versions)

These alternatives have varying trade-offs in terms of ease of use, performance, and browser support.

Keep in mind that the Fetch API is a modern standard, but it may not be supported by older browsers or devices. If you need to support older browsers, consider using alternative libraries like Axios or Request, which provide more comprehensive browser support.
