Benchmark: jQuery vs javascript loop

HTML Preparation code:

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.0.min.js"></script>
<div id="testElement"></div>

Tests:

jQuery
var lista = []; for(var i = 0; i < 100000; i++){ lista.push(i); } $(lista).each(function(x){ var b = x+1; });
Loop Vanilla JS
var lista = []; for(var i = 0; i < 100000; i++){ lista.push(i); } lista.forEach(x => {var b = x+1})

Let's break down the provided benchmark and explain what's being tested, compared options, pros and cons of each approach, library usage, special JavaScript features or syntax, and alternative solutions.

**Benchmark Definition**

The benchmark is defined in two test cases:

1. "jQuery vs javascript loop" - This is the overall benchmark name, which compares the speed of getting an element by its ID using jQuery versus a vanilla JavaScript loop.
2. The individual test case: "var lista = [];\r\nfor(var i = 0; i < 100000; i++){\r\n  lista.push(i);\r\n}\r\n$(lista).each(function(x){\r\n  var b = x+1;\r\n});" - This is the JavaScript code that gets executed by jQuery.
3. The second individual test case: "var lista = [];\r\nfor(var i = 0; i < 100000; i++){\r\n  lista.push(i);\r\n}\r\nlista.forEach(x => {var b = x+1})" - This is the equivalent vanilla JavaScript code.

**Comparison Options**

The benchmark compares two approaches:

1. **jQuery**: Uses jQuery's `each` method to iterate over the array and execute the callback function.
2. **Vanilla JS Loop**: Uses a traditional `for` loop with an array `forEach` method or simply iterates over the array using a `for` loop.

**Pros and Cons of Each Approach**

1. **jQuery**
	* Pros:
		+ Easier to write, especially for DOM manipulation tasks.
		+ Provides a convenient way to handle events and other tasks in a declarative style.
	* Cons:
		+ Adds extra overhead due to the library's functionality.
		+ Can be slower than native JavaScript code when execution speed is critical.
2. **Vanilla JS Loop**
	* Pros:
		+ Faster execution speed compared to jQuery.
		+ No additional library overhead.
	* Cons:
		+ More verbose and error-prone due to the need for manual looping.

**Library Usage**

The benchmark uses the jQuery library, specifically version 3.1.0, which provides the `each` method used in the test case.

**Special JavaScript Features or Syntax**

None mentioned in this specific benchmark.

**Alternative Solutions**

Other alternatives could include:

1. **Lodash**: A popular utility library that provides a `forEach` function similar to jQuery's `each`.
2. **Vanilla JavaScript alternatives**: Other libraries like `ramda` or `es6-promise` provide functional programming utilities, including `forEach`, which might be more efficient than the vanilla JavaScript implementation.
3. **Native Web APIs**: Instead of using `forEach`, you could use native web APIs like `Array.prototype.forEach()` (supported in most browsers) or `Array.prototype.forEach.call()`.
4. **Other loop alternatives**: Depending on the specific use case, other loops like `while` or `do-while` might be more suitable.

Keep in mind that the choice of approach depends on the specific requirements and constraints of your project. The benchmark result is meant to provide a general idea of which approach is faster for this particular task.
