Benchmark: lodash vs es6 in map 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 map method
var result = _.map(array, (arr) => { return arr.age > 26; });
es6 map method
var result = array.map((arr) => { return arr.age > 26; });

**What is tested on the provided JSON?**

The provided JSON represents a JavaScript microbenchmark test case for comparing the performance of two different approaches: Lodash's `map` function and the native ES6 `map` method.

**Options compared**

Two options are compared:

1. **Lodash's `map` function**: This is a popular utility library that provides various functions to manipulate arrays and objects. The `map` function applies a given callback function to each element of an array, returning a new array with the transformed values.
2. **Native ES6 `map` method**: This is a built-in JavaScript method that allows you to apply a transformation function to every element in an array.

**Pros and cons**

Here's a brief summary of the pros and cons of each approach:

**Lodash's `map` function:**

Pros:

* Widely supported and well-maintained library with many utility functions.
* Can be useful for complex transformations or when working with legacy codebases.

Cons:

* Adds overhead due to the need to include an external library.
* May not be as fast as native JavaScript, especially for small arrays.

**Native ES6 `map` method:**

Pros:

* Fast and lightweight, without the need for an additional library.
* Takes advantage of modern JavaScript features.

Cons:

* Requires support for ES6+ syntax, which may not be available in older browsers or environments.
* May require more manual testing to ensure compatibility with different browsers and versions.

**Other considerations**

* The test case uses a simple array transformation as the benchmark, so the results may not accurately reflect performance differences in more complex scenarios.
* The use of Lodash's `map` function might skew the results towards older or less modern environments that still support the library.

**Library used (Lodash)**

Lodash is a popular JavaScript utility library developed by Isaac Schlueter. It provides various functions for manipulating arrays, objects, and strings, among other things. In this test case, Lodash's `map` function is used to transform an array of objects based on a given condition.

**Special JS feature or syntax**

The test case uses ES6+ syntax (specifically, the arrow function notation) in both benchmark definitions. This syntax is supported by modern JavaScript engines but may not be available in older browsers or environments.
