Benchmark: Lodash max vs JS Math.max (2022)

HTML Preparation code:

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

Script Preparation code:

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}

var arr = [];
for(var i = 0; i < 1000; i++){
  arr.push({value:getRandomInt(100)});
}

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

**Benchmark Definition**

The benchmark is comparing two approaches to find the maximum value in an array: using JavaScript's built-in `Math.max()` function versus using the popular utility library Lodash's `_.max()` function.

**Script Preparation Code**

The script preparation code generates a random array of 1000 objects, each with a random integer value between 1 and 100. This is done to create a large dataset that can be used to measure performance.

**Html Preparation Code**

The HTML preparation code includes a script tag that loads the Lodash library from a CDN. This allows us to test both native JavaScript's `Math.max()` function and the Lodash version in the same benchmark.

**Individual Test Cases**

There are two individual test cases:

1. **Native js Math.max**: Tests the performance of using JavaScript's built-in `Math.max()` function.
2. **Lodash max**: Tests the performance of using Lodash's `_.max()` function.

**Pros and Cons:**

* **Native js Math.max**: Pros:
	+ Widely supported and optimized by browsers.
	+ Typically faster since it's a native function.
Cons:
	+ May not be as robust or customizable as other approaches.
* **Lodash max**: Pros:
	+ More flexible and customizable than native `Math.max()`.
	+ Can handle more complex data structures and edge cases.
Cons:
	+ Slower due to the overhead of loading and executing a library function.
	+ May not be supported by older browsers or systems.

**Library: Lodash**

Lodash is a popular utility library for JavaScript that provides a wide range of functions for tasks like array manipulation, object manipulation, and more. In this benchmark, it's used for its `_.max()` function, which implements a efficient algorithm for finding the maximum value in an array.

**Special JS Feature/Syntax: None**

There are no special JavaScript features or syntax being tested in this benchmark.

**Other Alternatives:**

If you wanted to test alternative approaches, you could consider using other libraries like:

* **Array.prototype.max()` (ES6+): A more modern and efficient approach that's supported by many browsers.
* **Math.max.apply()`: An older approach that uses `Math.max()` with the `apply()` method to apply it to an array.

Keep in mind that these alternatives might have different performance characteristics, so they'd need to be tested separately.
