Benchmark: lodash vs es6 in every method

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var array = [
  { 'name': 'lim', 'age': 26 },
  { 'name': 'kim', 'age': 28 },
  { 'name': 'choi', 'age': 32 },
  { 'name': 'park', 'age': 21 }
 ];

Tests:

lodash every method
var result = _.every(array, (arr) => { return arr.age > 19; });
es6 every method
var result = array.every((arr) => { return arr.age > 19; });

I'll break down the provided benchmark definition and test cases to help explain what's being tested.

**Benchmark Definition JSON**

The JSON represents a JavaScript microbenchmarking test case created using MeasureThat.net. It contains information about the benchmark, such as its name, description, script preparation code, and HTML preparation code (which includes a reference to the Lodash library).

**Script Preparation Code**

The script preparation code defines an array `array` with four objects, each containing a `name` and an `age`. This data structure is used to test various methods.

**Html Preparation Code**

The HTML preparation code links to the Lodash library (version 4.17.5) in its minified form, which is likely included in the browser's context when running the benchmark.

**Individual Test Cases**

Two test cases are defined:

1. **Lodash every method**: This test case uses the `_` object from the Lodash library and calls the `every()` method on the `array` with a callback function that checks if each object's age is greater than 19.
2. **ES6 every method**: This test case does not use any external library, but instead uses the native JavaScript `every()` method to iterate over the same array and perform the same check.

**What is being tested?**

Both test cases are comparing the performance of different approaches for checking if all elements in an array satisfy a certain condition. Specifically:

* Lodash's `every()` method with a callback function.
* Native JavaScript's `every()` method without any external libraries.

**Options compared**

The two options being compared are:

* Using a library (Lodash) to implement the `every()` method.
* Implementing the `every()` method using native JavaScript syntax.

**Pros and Cons of each approach:**

1. **Using Lodash's every() method**:
	* Pros:
		+ Easier to write and maintain, especially for complex conditions.
		+ Provides additional features like memoization and caching (not used in this benchmark).
	* Cons:
		+ Adds overhead due to the library itself and its execution time.
2. **Using native JavaScript's every() method**:
	* Pros:
		+ No additional overhead from a library, making it potentially faster.
		+ More efficient use of CPU resources since it doesn't require loading an external library.
	* Cons:
		+ May require more complex code for certain conditions.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides various functions for common tasks like array manipulation, object transformation, and more. In this benchmark, the `every()` method from Lodash is used to test its performance.

**Special JS feature/syntax: None mentioned**

Since there's no specific mention of any new or experimental features in the benchmark definition, I won't comment on them.

**Other alternatives**

For testing similar benchmarks, you could consider using other libraries like:

* Ramda (a functional programming library with various array functions).
* Underscore.js (another utility library that provides many functional programming utilities).

Keep in mind that these alternatives would introduce additional overhead and might not provide significant differences in performance compared to the native JavaScript implementation.

When preparing a benchmark, it's essential to consider the specific use case and requirements. In this example, using Lodash's `every()` method is convenient but may come with an overhead, while the native JavaScript implementation provides a more straightforward solution.
