Tests:

Lodash cloneDeep
myCopy = _.cloneDeep(MyObject);
Json clone
myCopy = JSON.parse(JSON.stringify(MyObject));
Ramda clone
myCopy = R.clone(MyObject);
Pvorb Clone
myCopy = clone(MyObject, false);

Let's break down the provided JSON data and explain what's being tested, compared, and some considerations for each approach.

**Benchmark Purpose:**

The benchmark is comparing the performance of four different cloning libraries in JavaScript:

1. Lodash (cloneDeep)
2. JSON Clone
3. Ramda
4. Pvorb Clone

These libraries are used to create deep copies of an object, which can be useful in various scenarios such as testing, debugging, and data processing.

**Comparison Options:**

The benchmark is comparing the execution speed (in executions per second) of each library when creating a deep copy of a complex object (`MyObject`).

Here's a brief overview of each library:

1. **Lodash (cloneDeep)**: A popular JavaScript utility library that provides functional programming helpers, including `cloneDeep`, which creates a deep clone of an object.
2. **JSON Clone**: A lightweight library that implements the JSON clone algorithm to create a deep copy of an object.
3. **Ramda**: A functional programming library for JavaScript that includes a `clone` function to create a deep clone of an object.
4. **Pvorb Clone**: Another cloning library that provides a way to create a deep copy of an object.

**Pros and Cons:**

Here's a brief summary of the pros and cons of each approach:

1. **Lodash (cloneDeep)**:
	* Pros: Well-maintained, widely used, and extensively tested.
	* Cons: Adds an extra dependency to your project.
2. **JSON Clone**:
	* Pros: Lightweight, easy to use, and no dependencies.
	* Cons: May not be as efficient or robust as other libraries.
3. **Ramda**:
	* Pros: Provides a functional programming perspective, which can be beneficial for certain use cases.
	* Cons: Steeper learning curve due to its functional programming approach.
4. **Pvorb Clone**:
	* Pros: Simple and lightweight, with minimal dependencies.
	* Cons: May not have the same level of testing or support as other libraries.

**Library and Purpose:**

* **Lodash (cloneDeep)**: Creates a deep clone of an object using its `cloneDeep` function.
* **JSON Clone**: Creates a deep copy of an object by recursively cloning each property, following the JSON clone algorithm.
* **Ramda**: Uses its `clone` function to create a deep clone of an object, which is then implemented as a higher-order function that takes an object and returns a cloned version.

**Special JS Feature/Syntax:**

The benchmark does not use any special JavaScript features or syntax. The code is straightforward and uses standard JavaScript objects and cloning functions.

**Alternatives:**

If you're looking for alternative libraries, consider:

* **Immutable.js**: A library that provides a way to create immutable data structures, which can be useful in certain scenarios.
* **DeepClone**: A lightweight library that creates deep clones of objects using a simple algorithm.
* **Splice**: A modern JavaScript library that provides a way to manipulate and clone objects in a functional programming style.

Keep in mind that the choice of library ultimately depends on your specific use case, project requirements, and personal preference.
