Benchmark: Lodash every vs native every test

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js'></script>

Script Preparation code:

var array = Array.from({length: 10000}, () => ({
    age: Math.floor(Math.random() * 100)
}));

Tests:

Lodash test
var result = _.every(array, (arr) => { return arr.age > 19; });
Native test
var result = array.every((arr) => { return arr.age > 19; });

Let's break down what's being tested in the provided JSON.

**Benchmark Definition**

The benchmark is comparing two approaches to check if every element in an array satisfies a certain condition. The first approach uses the `lodash` library, specifically its `every()` function. The second approach uses the native JavaScript `every()` method.

**Options Compared**

The options being compared are:

1. Using the `lodash` library (`Lodash test`) vs.
2. Using the native JavaScript `every()` method (`Native test`)

**Pros and Cons of Each Approach**

1. **Using `lodash` library (`Lodash test`)**:
	* Pros:
		+ Provides a more concise and readable way to write the condition using a higher-order function (curry).
		+ Might be faster due to optimized implementation in `lodash`.
	* Cons:
		+ Adds an external dependency, which can lead to slower startup times.
		+ May introduce additional overhead due to the library's existence.
2. **Using native JavaScript `every()` method (`Native test`)**:
	* Pros:
		+ No dependencies or overhead, as it's a built-in method.
		+ Can be optimized by the V8 engine (JavaScript engine used by Chrome).
	* Cons:
		+ Requires more verbose code to write the condition using an arrow function.
		+ Might be slower due to the lack of optimization in `lodash`.

**Library and Its Purpose**

The `lodash` library is a popular utility library that provides a collection of helper functions for tasks such as array manipulation, string manipulation, and more. In this case, it's used to provide a concise way to write the condition using a higher-order function (curry).

**Special JS Feature or Syntax**

There is no special JavaScript feature or syntax being tested in this benchmark.

**Other Alternatives**

If you wanted to compare the performance of these two approaches without relying on `lodash`, you could also consider:

1. Using another utility library like `underscore.js` or `ramda`.
2. Implementing a custom implementation for the `every()` method using only native JavaScript.
3. Measuring the performance of each approach using different browsers, devices, or environments.

Note that these alternatives would require additional setup and testing to ensure accurate results.
