Benchmark: Object array using find vs lodash find

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.core.js"></script>

Tests:

object array find
var a = [{marble: "hihi0", text:'hello'}, {marble: "hihi1", text:'a'}, {marble: "hihi2", text:'bc'}]; var b = a.find(item => item.marble === 'hihi1');
object array _.find
var a = [{marble: "hihi0", text:'hello'}, {marble: "hihi1", text:'a'}, {marble: "hihi2", text:'bc'}]; var b = _.find(a, {marble: "hihi1"});

Let's break down the provided benchmark and explain what is tested, compared options, pros and cons, and other considerations.

**Benchmark Overview**

MeasureThat.net is a website where users can create and run JavaScript microbenchmarks to compare different approaches. The provided benchmark compares two ways of finding an object in an array: using the `find` method without any additional library (built-in JavaScript) versus using the `_` variable from the Lodash library.

**Options Compared**

Two options are compared:

1. **Built-in `find` method**: This is a standard JavaScript method that searches for an element with a given condition in an array.
2. **Lodash `_find` function**: Lodash is a popular JavaScript utility library that provides various functions, including `_find`, which performs the same operation as the built-in `find` method.

**Pros and Cons**

* **Built-in `find` method**:
	+ Pros: Native JavaScript implementation, simple to use.
	+ Cons: May not be optimized for performance or have additional features like Lodash.
* **Lodash `_find` function**:
	+ Pros: Can be faster than the built-in `find` method due to optimization, and provides additional functionality (e.g., support for promises).
	+ Cons: Requires an external library, may add overhead due to HTTP request or bundle size.

**Library Used**

In this benchmark, Lodash is used. Specifically, it's version 4.17.5. The `_` variable from Lodash is used to invoke the `_find` function. The purpose of Lodash is to provide a set of reusable functions that make common programming tasks easier and more efficient.

**Special JS Features or Syntax**

There are no special JavaScript features or syntax mentioned in this benchmark. Both examples use standard JavaScript syntax for defining arrays, variables, and conditional statements.

**Other Considerations**

* **Performance overhead**: The Lodash library can introduce performance overhead due to HTTP requests or bundle size. However, in this specific benchmark, the Lodash `_find` function might be faster than the built-in `find` method.
* **Feature parity**: If you don't use Lodash or similar libraries, you'll need to implement the `_find` functionality yourself, which can add development overhead and complexity.

**Alternatives**

If you don't want to use an external library like Lodash, you could:

1. Implement your own `_find` function using a standard JavaScript `for` loop or other methods.
2. Use another library that provides similar functionality, such as the `lodash-es` version (ES6+ compatible) or the `underscore` library.

Keep in mind that alternatives might not offer the same level of optimization and performance as Lodash's `_find` function.
