Benchmark: lodash vs es6 in some 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 some method
var result = _.some(array, (arr) => { return arr.age === 32; });
es6 some method
var result = array.some((arr) => { return arr.age === 32; });

**Benchmark Explanation**

The provided JSON represents a JavaScript microbenchmark test case on the MeasureThat.net website. The test compares two approaches to check if an array contains a specific value using the `some()` method: the original ECMAScript 6 (ES6) implementation and Lodash's implementation.

**Options Compared**

Two options are compared:

1. **Original ES6 implementation**: This is the native JavaScript implementation of the `some()` method, which was introduced in ES6.
2. **Lodash's implementation**: This is a utility library developed by Isaac Schlueter that provides an additional `some()` function for working with arrays.

**Pros and Cons**

* **Native ES6 implementation:**
	+ Pros:
		- Built-in functionality, no external dependency
		- Optimized for performance
	+ Cons:
		- May not be as readable or maintainable due to its concise syntax
		- Not compatible with older browsers that don't support ES6
* **Lodash's implementation:**
	+ Pros:
		- More readable and maintainable code structure
		- Can be useful for developers who prefer a more explicit approach
	+ Cons:
		- Adds an external dependency (the Lodash library)
		- May have a slight performance overhead due to the function call

**Library Usage**

In this benchmark, the `lodash` library is used in its full form, specifically importing the entire `lodash.min.js` file. The `lodash` library provides various utility functions, including the `some()` method.

**Special JS Features or Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark that would require a deep understanding of advanced concepts.

**Other Alternatives**

If you prefer not to use Lodash, other alternatives for the `some()` function include:

* Using the native array methods `every()` and `some()` together: `array.some((arr) => arr.every((item) => item !== 32));`
* Creating a custom function to achieve the same result
* Using a third-party library like **Underscore.js**, which provides similar functionality to Lodash

Keep in mind that these alternatives may have different performance characteristics and usage scenarios.

**Benchmark Preparation Code**

The `Script Preparation Code` section sets up an array of objects with an "age" property. The `Html Preparation Code` section imports the `lodash.min.js` file, making it available for use in the benchmark tests.

By analyzing this JSON data, you can understand that the benchmark compares two approaches to checking if an array contains a specific value using the `some()` method: the original ES6 implementation and Lodash's implementation.
