Benchmark: Find: Native vs Underscore 1.13 vs Lodash 4.17

HTML Preparation code:


<script src='https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js'></script>
<script src='https://cdn.jsdelivr.net/npm/underscore@1.13.1/underscore-umd-min.js'></script>

Script Preparation code:

var users = [
  { 'user': 'joey',  'age': 32 },
  { 'user': 'ross',    'age': 41 },
  { 'user': 'chandler', 'age': 39 },

// Underscore was loaded last, so this saves an instance of underscore and resets _ to it's previous value (lodash).
var _underscore = _.noConflict();
// This saves an instance of lodash and resets _ to it's previous value (undefined).
var _lodash = _.noConflict();

Tests:

Native
users.find(function (o) { return o.age < 40; })
Underscore
_underscore.find(users, function (o) { return o.age < 40; })
Lodash
_lodash.find(users, function (o) { return o.age < 40; })

Let's dive into the world of JavaScript microbenchmarks.

**Benchmark Definition**

The provided JSON represents a benchmark test that compares the performance of three different libraries: Native (built-in JavaScript), Underscore.js, and Lodash.js.

The test case uses an array of objects (`users`) to simulate a common use case for finding elements in an array based on a condition. The condition is `o.age < 40`.

**Options Compared**

The options compared are:

1. Native (built-in JavaScript): This option tests the performance of the built-in JavaScript `find()` method.
2. Underscore.js: This option tests the performance of the Underscore.js library's `find()` method, which is a popular utility library for functional programming in JavaScript.
3. Lodash.js: This option tests the performance of the Lodash.js library's `find()` method, which builds upon Underscore.js and adds more functionality.

**Pros and Cons**

Here are some pros and cons of each approach:

1. Native (built-in JavaScript):
	* Pros:
		+ Built-in, so no additional dependencies to worry about.
		+ Can be optimized by the JavaScript engine.
	* Cons:
		+ May not be as efficient as optimized third-party libraries.
2. Underscore.js:
	* Pros:
		+ Well-maintained and widely adopted library.
		+ Provides a consistent API for functional programming.
	* Cons:
		+ Adds an extra dependency to the project.
		+ May have performance overhead due to the library's functionality.
3. Lodash.js:
	* Pros:
		+ Builds upon Underscore.js, so provides more features and optimization.
		+ Still widely adopted and well-maintained.
	* Cons:
		+ Adds two extra dependencies (Underscore.js and Lodash.js).
		+ May have performance overhead due to the additional functionality.

**Library Used**

The test case uses:

1. Underscore.js: `_underscore.find(users, function (o) { return o.age < 40; })`
	* Purpose: Provides a consistent API for functional programming in JavaScript.
2. Lodash.js: `_lodash.find(users, function (o) { return o.age < 40; })`
	* Purpose: Builds upon Underscore.js and adds more functionality, including additional optimization.

**Special JS Feature or Syntax**

There is no special JS feature or syntax used in this benchmark test.

**Other Alternatives**

If you wanted to compare the performance of other libraries or built-in methods, here are some alternatives:

1. Other utility libraries: You could replace Underscore.js and Lodash.js with other popular utility libraries like Moment.js, jQuery, or even vanilla JavaScript's `filter()` method.
2. Built-in methods: You could use other built-in JavaScript methods like `Array.prototype.filter()`, `Array.prototype.map()`, or `Array.prototype.reduce()` to compare their performance.
3. Other frameworks or libraries: Depending on the specific use case, you might want to consider using other frameworks or libraries that provide similar functionality, such as React, Angular, or Vue.js.

I hope this explanation helps!
