Benchmark: Yet another lodash vs es6

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/3.10.1/lodash.min.js'></script>

Script Preparation code:

function minBy (arr, iteratee){
  const func = typeof iteratee === 'function' ? iteratee : item => item[iteratee]
  const min = Math.min(...arr.map(func))
  return arr.find(item => func(item) === min)
}
function getValue(x){
  return Math.sin(x);
}
var data = [...Array(20)].map((v, idx) => idx);

Tests:

Native minBy
minBy(data, getValue);
Lodash 3.10.1 min
_.min(data, getValue);

Let's break down the provided benchmark and explain what's being tested.

**Benchmark Overview**

The benchmark compares two approaches to find the minimum element in an array:

1. **ES6 Native `minBy`**: Uses the built-in `minBy` function from JavaScript's standard library (ECMAScript 2017).
2. **Lodash 3.10.1 `min`**: Uses a utility function called `min` from Lodash, a popular JavaScript library for functional programming.

**Options Compared**

The two options are compared in terms of performance and execution speed.

**Pros and Cons**

* **ES6 Native `minBy`**:
	+ Pros: Built-in function, likely to be optimized by the browser's JavaScript engine.
	+ Cons: Might not be supported in older browsers or versions.
* **Lodash 3.10.1 `min`**:
	+ Pros: Widely used and well-maintained library, likely to have better performance for complex use cases.
	+ Cons: Adds extra overhead due to the inclusion of a separate library.

**Library and Syntax**

The benchmark uses Lodash version 3.10.1, which is an older version of the library. The `min` function from Lodash takes two arguments: the input array and a callback function that defines the comparison logic.

In this specific case, the callback function passed to `min` is simply `getValue`, which returns the sine of its argument (not directly relevant to finding the minimum value).

**Special JS Feature or Syntax**

There's no special JavaScript feature or syntax used in this benchmark. The code uses standard JavaScript features and syntax.

**Other Alternatives**

For implementing `minBy`, other approaches include:

1. Using a sorting algorithm with a starting index, like binary search.
2. Using a custom implementation of the minimum value function, optimized for performance.
3. Leveraging existing libraries or frameworks that provide similar functionality.

In summary, the benchmark compares the performance of two approaches to find the minimum element in an array: ES6 Native `minBy` and Lodash 3.10.1 `min`. The native approach is likely to be faster due to its built-in nature, but might not work in older browsers or versions. Lodash's `min` function provides a more robust solution but adds extra overhead due to the library inclusion.
