Script Preparation code:

const box = $('.btn-check');

Tests:

jQuery filter
const box = $('.btn-check'); const check = box.filter('.default').length == box.filter('.default').length;
every
const box = $('.btn-check'); const check2 = box.filter('.default').get().every(i => i.checked);

**Benchmark Overview**

The provided benchmark is designed to compare the performance of two approaches: `filter` and `every` methods on JavaScript arrays, specifically in the context of filtering checkboxes using jQuery.

**Library and Purpose**

The library used in this benchmark is jQuery, a popular JavaScript library for DOM manipulation and event handling. The `filter` method is used to create a new array containing only the elements that pass the test implemented by the provided function. In this case, the filter function checks if an element has a class of "default". The `every` method returns true if all elements in an array satisfy the condition.

**Options Compared**

Two options are compared:

1. **jQuery Filter (`filter` method)**: This approach uses the `filter` method to create a new array containing only the elements that have a class of "default".
2. **Every Method (`every` method)**: This approach uses the `every` method to check if all elements in the filtered array satisfy the condition (i.e., they have a class of "default").

**Pros and Cons**

* **jQuery Filter (`filter` method)**
	+ Pros:
		- Easy to read and understand
		- Fast execution time due to optimized implementation by jQuery
	+ Cons:
		- May not be as efficient as other methods for very large arrays
		- Requires jQuery library to be included
* **Every Method (`every` method)**
	+ Pros:
		- Can be more efficient than `filter` for very large arrays
		- Does not require a separate loop or iteration over the array
	+ Cons:
		- May have performance issues if the condition is complex or expensive to evaluate
		- Less intuitive for developers without prior experience with the method

**Other Considerations**

* **DOM Manipulation**: Both approaches involve DOM manipulation, which can introduce additional overhead due to garbage collection and reflow.
* **Browser Variability**: The benchmark results may vary across different browsers, as each browser has its own quirks and optimizations.

**Special JS Features or Syntax**

None mentioned in the provided code snippets. However, it's worth noting that the `every` method is a modern JavaScript feature introduced in ECMAScript 2019.

**Alternatives**

Other alternatives for filtering arrays include:

* Using `forEach` loop with a callback function
* Using `reduce` method to create a new array containing only the elements that meet the condition
* Using a custom implementation without relying on built-in methods (e.g., using a single loop over the array)
