Let's dive into the benchmark.

**Benchmark Purpose**
The benchmark is designed to compare the performance of three different methods for creating a deep copy of an object: Lodash, Angular, and JSON cloning.

**Script Preparation Code**
The script prepares an object `MyObject` with nested properties, including a property `jayson` that contains a string representation of the `JSON.stringify()` method. This is likely done to test the library's handling of nested objects and arrays.

**Html Preparation Code**
The HTML code includes scripts from AngularJS (1.2.0) and Lodash (4.17.5), which are used as libraries in the benchmark.

**Individual Test Cases**

1. **Lodash Clone**: The first test case uses the `_clone()` function from Lodash to create a deep copy of `MyObject`.
	* Library: Lodash
	* Purpose: Provides utility functions, including cloning.
2. **JSON Clone**: The second test case uses the `JSON.parse(JSON.stringify(MyObject))` syntax to create a deep copy of `MyObject`. This method is specific to JSON and converts the object to a string, then parses it back into an object.
	* Library: None (built-in JavaScript function)
	* Purpose: A simple, lightweight way to create a deep copy of an object.
3. **Angular Copy**: The third test case uses the `angular.copy()` function from AngularJS (1.2.0) to create a deep copy of `MyObject`.
	* Library: AngularJS
	* Purpose: Provides utility functions for copying and manipulating data.

**Pros and Cons**

1. **Lodash Clone**
	* Pros:
		+ Flexible and powerful cloning functionality.
		+ Can handle complex objects with nested properties.
	* Cons:
		+ Adds dependency on Lodash library.
		+ May have overhead due to the larger library size.
2. **JSON Clone**
	* Pros:
		+ Lightweight and simple implementation.
		+ Does not add any external dependencies.
	* Cons:
		+ May not handle complex objects or nested properties well.
		+ Can be slower than Lodash clone for large datasets.
3. **Angular Copy**
	* Pros:
		+ Built-in functionality in AngularJS, so no additional dependency is required.
		+ Handles complex objects and nested properties well.
	* Cons:
		+ Limited availability, as it's an older version of AngularJS.

**Other Considerations**

* The benchmark uses a relatively small dataset (`MyObject`) to compare the three methods. A larger dataset would provide more accurate results, especially for performance-intensive operations.
* The benchmark does not account for potential memory leaks or other issues that may arise when working with deep copies in JavaScript.

**Alternatives**
If you need alternative methods for creating deep copies, consider:

1. `Object.assign()`: A built-in JavaScript method that can be used to create a shallow copy of an object.
2. `Array.prototype.slice()`: A built-in JavaScript method that can be used to create a shallow copy of an array.
3. `lodash.cloneDeep()`: An alternative implementation of the `_clone()` function from Lodash, which is specifically designed for deep cloning.

In summary, the benchmark provides a clear comparison of three methods for creating deep copies in JavaScript: Lodash clone, JSON clone, and Angular copy. The choice of method depends on your specific requirements, such as performance, complexity, and dependency management.
