Benchmark: Lodash vs Native deep clone

HTML Preparation code:

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

Script Preparation code:

var objects = [{ 'a': 1 }, { 'b': 2 }];

Tests:

Lodash
var deep = _.cloneDeep(objects); console.log(deep);
Native
var deep1 = JSON.parse(JSON.stringify(objects)); console.log(deep1);

**Benchmark Overview**

The provided JSON represents a benchmark test comparing two approaches to create a deep clone of an object: Lodash and native JavaScript.

**Options Compared**

Two options are being compared:

1. **Lodash**: The Lodash library is used to create a deep clone of the `objects` array using the `_cloneDeep` function.
2. **Native**: A native JavaScript approach is used to create a deep clone of the `objects` array by serializing the object to a string, parsing it back to an object, and then deserializing it back to an original object.

**Pros and Cons**

**Lodash:**

Pros:

* Faster execution time due to optimized implementation
* Easier to use, especially for complex data structures

Cons:

* Requires including an additional library in the benchmark
* May introduce overhead due to dependency injection

**Native:**

Pros:

* No external dependencies required
* Often faster execution time due to being a native operation

Cons:

* More verbose and error-prone code
* Limited support for complex data structures

**Other Considerations**

Both approaches have their strengths and weaknesses. The Lodash approach is generally faster and more convenient, but requires an additional dependency. The native approach is often faster but more error-prone and verbose.

**Library and Its Purpose (Lodash)**

Lodash is a popular JavaScript utility library that provides various functions for tasks like array manipulation, object creation, and string manipulation. In this benchmark, the `_cloneDeep` function is used to create a deep clone of an object, which is a key feature of Lodash.

**Special JS Feature or Syntax (None)**

There are no special JavaScript features or syntax used in this benchmark.

**Benchmark Preparation Code**

The provided Script Preparation Code creates an `objects` array with two properties: `'a'` and `'b'`, and the Html Preparation Code includes a script tag that loads the Lodash library from a CDN.

**Individual Test Cases**

Each test case runs a specific benchmark:

1. **Lodash**: The `_cloneDeep` function is called on the `objects` array, and the resulting cloned object is logged to the console.
2. **Native**: A native JavaScript approach is used to create a deep clone of the `objects` array by serializing it to a string using `JSON.stringify`, parsing it back to an object using `JSON.parse`, and then deserializing it back to an original object.

**Latest Benchmark Result**

The provided JSON represents the benchmark result, which shows the execution time per second for each test case (Lodash and Native) on a specific browser configuration.
