Benchmark: Lodash vs Javascript benchmarks DrewM4

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var MyObject = {
  description: 'Creates a deep copy of source, which should be an object or an array.',
  myNumber: 123456789,
  myBoolean: true,
  jayson: {
    stringify: 'JSON.stringify() method converts a JavaScript value to a JSON string....',
    parse: 'JSON.parse() method parses a JSON string...'
  }
};

var myCopy = null;

Tests:

Lodash Get
let jayson = "jayson" let stringify = "stringify" myCopy = _.get(MyObject, `${jayson}.${stringify}`);
Javascript
myCopy = MyObject === undefined || MyObject["jayson"] === undefined || MyObject["jayson"]["stringify"] === undefined ? undefined : MyObject["jayson"]["stringify"];

Let's break down what is being tested in the provided JSON.

**Benchmark Overview**

The benchmark compares two approaches to accessing nested properties of an object: using Lodash (a popular utility library for JavaScript) and using native JavaScript syntax.

**Script Preparation Code**

The script preparation code defines a test object `MyObject` with several properties, including `myNumber`, `myBoolean`, and a nested object `jayson`. The `jayson` object has two properties: `stringify` and another property with the same name. This setup is likely intended to create a deep copy of the original object using Lodash.

**Html Preparation Code**

The HTML preparation code includes a script tag that loads the Lodash library (version 4.17.5).

**Individual Test Cases**

There are two test cases:

1. **Lodash Get**: This test case uses the `_.get()` method from Lodash to access the nested property `jayson.stringify`. The purpose of this test is to compare the performance of using Lodash's utility function versus native JavaScript syntax.
2. **Javascript**: This test case uses native JavaScript syntax to access the same nested property `jayson.stringify`, checking if it exists and returning its value if it does.

**Pros and Cons**

* **Lodash Get**
	+ Pros:
		- Easier to read and maintain, as it clearly expresses the intent of accessing a nested property.
		- Less error-prone, as Lodash handles the property access internally.
	+ Cons:
		- Slower performance due to the overhead of the utility function.
* **Javascript**
	+ Pros:
		- Faster performance, as native syntax does not incur additional function call overhead.
	+ Cons:
		- More verbose and error-prone, requiring manual management of property access.

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides various functions for common tasks, such as array manipulation, object transformation, and stringification. In this case, the `_get()` method is used to safely navigate nested objects and retrieve values.

**Special JS Feature/Syntax**

The benchmark uses the `_.get()` method, which is a shorthand way of accessing nested properties using Lodash. This syntax is not specific to any particular JavaScript standard or feature, but rather a convenience provided by the Lodash library.

Now, if you're interested in other alternatives for accessing nested properties, here are some options:

* Using the `in` operator and bracket notation (`MyObject['jayson.stringify']`)
* Using the `hasOwnProperty()` method to check for existence before accessing the property
* Using a recursive function to traverse the object structure

However, Lodash's `_get()` method remains a popular choice for its convenience, readability, and safety features.
