Benchmark: computedstyle vs innerwidth

HTML Preparation code:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<style>
  #test { 
background: red; 
width: 100px; 
height: 100px;
border: 5px solid #406c23;
}

</style>

<div id='test'>yellow this is a test</div>

Script Preparation code:

var $ele = $('#test');
var elem = document.getElementById("test");

Tests:

jquery
$ele.innerWidth();

Let's break down the provided benchmark and explain what's being tested, compared, and the pros/cons of each approach.

**Benchmark Context**

The test measures which method is faster to get the inner width of an element: using jQuery's `innerWidth()` or the native `getComputedStyle(elem).width` approach.

**Options Compared**

Two approaches are compared:

1. **jQuery (`$ele.innerWidth();`)**: This method uses jQuery, a popular JavaScript library for DOM manipulation and event handling.
2. **Native (`window.getComputedStyle(elem).width;`)**: This method uses the native `getComputedStyle()` function to access the element's styles.

**Pros/Cons of Each Approach**

**jQuery (`$ele.innerWidth();`)**
Pros:

* Easier to use, especially for web developers familiar with jQuery.
* Provides a more convenient way to get an element's inner width.

Cons:

* Adds extra overhead due to the jQuery library and its internal workings.
* May introduce additional DOM manipulation steps, potentially affecting performance.

**Native (`window.getComputedStyle(elem).width;`)**
Pros:

* Direct access to the native API, bypassing any additional libraries or wrappers.
* Can be faster since it doesn't involve additional processing or DOM manipulations.

Cons:

* Requires more manual effort and understanding of the underlying DOM and CSSOM APIs.
* May not be as convenient or readable for some developers.

**Library (jQuery) Purpose**

jQuery is a popular JavaScript library that simplifies DOM manipulation, event handling, and other tasks. In this benchmark, it's used to provide a convenient way to get an element's inner width using the `$ele.innerWidth()` method.

**Special JS Feature/Syntax (None)**

There are no special JavaScript features or syntaxes being tested in this benchmark. Both approaches use standard JavaScript methods.

**Other Alternatives**

If you wanted to test alternative approaches, here are some possibilities:

* Using a CSS-in-JS library like styled-components or emotion.
* Implementing the native `getComputedStyle()` function using a library like canvas or SVGs for rendering.
* Comparing other DOM manipulation libraries like React or Angular.

Keep in mind that these alternatives might introduce additional complexity and may not provide a direct comparison to the jQuery and native approaches.
