Benchmark: EGO Intersection lodash vs underscore

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/underscore@1.13.1/underscore-min.js"></script>

Script Preparation code:

var underscore = _.noConflict();
var array1 = ['bedroom', 'kitchen', 'bathroom', 'living room', 'indoors', 'outdoors', 'city', 'urban', 'villa', 'hotel'];
var array2 = ['bed', 'kitchen island', 'bath', 'room', 'city'];

Tests:

lodash
var arrayLodash = _.intersection(array1, array2);
underscore
var arrayUnderscore = underscore.intersection(array1, array2);

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

**Benchmark Overview**

The benchmark compares the performance of two popular JavaScript libraries: Lodash and Underscore. Both libraries provide utility functions for tasks like array manipulation, string manipulation, and more.

**Script Preparation Code**

The script preparation code is a crucial part of the benchmark. It sets up the environment by:

1. Loading both Lodash and Underscore libraries.
2. Creating two sample arrays: `array1` and `array2`.
3. Storing references to these arrays in variables `arrayLodash` and `arrayUnderscore`.

**Html Preparation Code**

The HTML preparation code includes links to the CDN hosts of both Lodash and Underscore libraries.

**Individual Test Cases**

There are two individual test cases:

1. **Lodash**: The benchmark definition is a simple call to the `intersection()` function on `array1` using the `arrayLodash` variable.
2. **Underscore**: The benchmark definition is similar, but uses the `underscore.intersection()` function instead.

**Options Compared**

The main difference between Lodash and Underscore is how they implement their functions. Here are some pros and cons of each approach:

* **Lodash:**
	+ Pros:
		- More comprehensive set of utility functions (over 100).
		- Better support for functional programming.
		- Easier to use, with a more consistent API.
	+ Cons:
		- Larger bundle size (~250KB).
		- Some users find the API too verbose or complex.
* **Underscore:**
	+ Pros:
		- Smaller bundle size (~80KB).
		- More lightweight and efficient, especially for small tasks.
		- Easier to learn and use for simple, low-level operations.
	+ Cons:
		- Fewer utility functions compared to Lodash (around 50).
		- Less support for functional programming.

**Library Overview**

* **Lodash**: A popular JavaScript library that provides a comprehensive set of utility functions for tasks like array manipulation, string manipulation, and more. It's designed for use in web development and is widely used in the industry.
* **Underscore**: Another popular JavaScript library that provides a smaller set of utility functions compared to Lodash. It was created by Jeremy Ashkenas, one of the creators of Prototype.js.

**Special JS Features/Syntax**

There are no specific special features or syntaxes being tested in this benchmark. The focus is on comparing the performance of two different libraries.

**Alternatives**

If you're considering using an alternative library for array manipulation and string manipulation tasks, some popular options include:

* **Moment.js**: A lightweight JavaScript library for working with dates and times.
* **JSZip**: A JavaScript library for working with ZIP archives.
* **Fastest**: A JavaScript library that aims to provide the fastest possible performance for common operations like array manipulation and string concatenation.

In terms of pure utility functions, you might also consider using a library like:

* **Immutable.js**: A library that provides immutable data structures and functional programming utilities.
* **Ramda**: A functional programming library that provides a small set of high-level functions for tasks like array filtering and mapping.
