Benchmark: vanilla vs jquery speed 2

HTML Preparation code:

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

Script Preparation code:

function $q(selector, context) {
    return (context || document).querySelectorAll(selector);
}

Tests:

vanilla add class
document.querySelector(".test").classList.add("next-class");
jquery add class
$(document).find(".test").addClass("next-class");
vanilla find element
document.querySelector(".test");
jquery find element
$(document).find(".test");
custom selector find element
$(".test", document);

Let's break down the provided JSON and explain what's being tested, compared, and analyzed.

**Benchmark Definition:**
The benchmark definition is a set of scripts that define how to create a microbenchmark for comparing different approaches. The script preparation code defines a jQuery-like function `$q(selector, context)` that returns an element selected by the `querySelectorAll` method. This allows users to write benchmarks using vanilla JavaScript and compare their performance with jQuery.

**Test Cases:**
The benchmark consists of five test cases, each testing a different approach:

1. **Vanilla Add Class**: Tests the performance of adding a class to an element using the `classList.add` method.
2. **jQuery Add Class**: Tests the performance of adding a class to an element using jQuery's `$()` function with `addClass`.
3. **Vanilla Find Element**: Tests the performance of finding an element by its CSS selector using the `querySelector` method.
4. **jQuery Find Element**: Tests the performance of finding an element by its CSS selector using jQuery's `$()` function with a context.
5. **Custom Selector Find Element**: Tests the performance of finding an element using a custom selector (not specified in the benchmark definition).

**Comparison:**
The benchmark compares the performance of each test case across different browsers and devices, collecting execution counts per second for each test.

**Pros and Cons of Each Approach:**

* **Vanilla Add Class**: Pros: Fast, lightweight, widely supported. Cons: Can be slower than jQuery due to browser differences.
* **jQuery Add Class**: Pros: Simplifies DOM manipulation, widely supported. Cons: Adds extra overhead due to jQuery's size and complexity.
* **Vanilla Find Element**: Pros: Fast, lightweight, flexible. Cons: Requires manual CSS selector implementation.
* **jQuery Find Element**: Pros: Convenient, widely supported. Cons: Adds extra overhead due to jQuery's size and complexity.

**Library:**
The benchmark uses the jQuery library for its `$()` function and `addClass` method.

**Special JS Features/Syntax:**
None mentioned explicitly in the provided code.

**Other Alternatives:**

* Other CSS selectors (e.g., `querySelector`, `querySelectorAll`) could be used to find elements.
* Other libraries or frameworks that provide similar functionality (e.g., React, Angular) could be used instead of jQuery.
* Alternative approaches for DOM manipulation and class addition (e.g., using a library like Polymer).

**Considerations:**
When writing microbenchmarks, it's essential to consider factors such as:

* The scope of the benchmark: Is it comparing specific use cases or general performance?
* The test environment: Are multiple browsers and devices being tested?
* The execution counts per second: Are they accurate and representative?
* The results' significance: How do the results apply to real-world scenarios?
