Benchmark: Lodash Remove v Native Filter

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>

Script Preparation code:

var max = 100000; 
var nums = [],
    rands = [];

for (var i = 0; i < max; i++) {
 const randBool = Math.floor(Math.random() * 2) === 1 ? true : false;
 nums.push(i);
 if (randBool) {
   rands.push(i);
 }
}

var temp = nums.slice();

Tests:

Vanilla
temp = temp.filter((item) => rands.includes(item));
Lodash
_.remove(temp, (item) => rands.includes(item));

**Benchmark Definition JSON**

The provided JSON defines a benchmark test case for removing elements from an array using two different approaches:

1. **Native Filter**: This approach uses the built-in `filter()` method of JavaScript arrays, which removes elements that don't match a given condition.
2. **Lodash Remove**: This approach uses the `remove()` function from the Lodash library, which is a utility library for functional programming in JavaScript.

**Options Compared**

The benchmark test case compares the performance of these two approaches:

* Native Filter (using JavaScript's built-in `filter()` method)
* Lodash Remove (using the `remove()` function from the Lodash library)

**Pros and Cons**

Here are some pros and cons of each approach:

Native Filter:
Pros:
	+ No external dependencies required
	+ Typically faster since it's a native implementation
Cons:
	+ May have performance issues in certain edge cases or with large datasets

Lodash Remove:
Pros:
	+ More concise code, which can lead to better maintainability and readability
	+ Often has built-in optimizations for performance
Cons:
	+ Requires an external library (Lodash), which may introduce overhead
	+ May not be as performant as a native implementation in some cases

**Library: Lodash**

The `_.remove()` function from the Lodash library is used to remove elements from an array. The purpose of this function is to provide a concise and efficient way to remove elements that match a given condition, without having to write custom code.

**Special JS Feature/Syntax**

There doesn't appear to be any special JavaScript features or syntax being tested in this benchmark case.

**Other Alternatives**

If you want to test other approaches for removing elements from an array, here are some alternatives:

1. **Using a loop**: You can use a simple loop to iterate over the array and remove elements that match a given condition.
2. **Using `Array.prototype.splice()`**: This method allows you to remove elements from an array by index or by value, but it has its own performance characteristics.

Some examples of alternative benchmark test cases might include:

* Native Filter with `.splice()` instead of `.filter()`
* Using a custom implementation (e.g., using a loop)
* Testing the performance of `Array.prototype.splice()` for removing elements from an array

Keep in mind that each approach has its own pros and cons, and the best choice will depend on the specific use case and requirements.
