Let's dive into explaining what is tested on the provided JSON benchmark.

**What is being tested?**

The benchmark measures the performance of two approaches to access a nested property in an object:

1. **Lodash.get**: This approach uses the Lodash library to safely navigate through the object and retrieve the value.
2. **Native Property Dot Notation with Sanity Check**: This approach uses the native JavaScript property dot notation (`person.name`) with an added sanity check to ensure that `person` is not null or undefined before attempting to access its properties.

**Options compared**

The two approaches are compared in terms of their performance, which is measured by the number of executions per second. The Lodash.get method uses a library to simplify the process, while the Native approach relies on native JavaScript syntax.

**Pros and Cons of each approach:**

* **Lodash.get**:
	+ Pros: Simplifies code and reduces chance of errors, provides better support for nested objects.
	+ Cons: Requires including an external library, may have a slight overhead due to its additional functionality.
* **Native Property Dot Notation with Sanity Check**:
	+ Pros: No additional dependencies required, direct access to native JavaScript features.
	+ Cons: May require more verbose code, and there's a risk of errors if the sanity check fails.

The sanity check in the Native approach ensures that `person` is not null or undefined before attempting to access its properties. This prevents potential errors when accessing nested properties.

**Library usage**

In this benchmark, Lodash is used as a library to simplify the process of accessing nested properties. The script preparation code includes a link to the Lodash CDN, which allows users to easily include the library in their test environment.

**Special JS feature or syntax (None)**

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

**Other alternatives**

Alternative approaches could include:

* Using other libraries like `get-object-value` or `accessor-macros`
* Implementing custom sanity checks
* Using a different property access method, such as bracket notation (`person['name']`)
* Using a functional programming approach with `function(person) { return person.name; }`

However, these alternatives may not be as straightforward to implement or maintain as the Lodash.get and Native approaches.

**Benchmark preparation code**

The script preparation code sets up an object `person` with nested properties. This allows users to easily test different property access methods in a controlled environment.

Overall, this benchmark provides a useful comparison of two common approaches to accessing nested properties in JavaScript, highlighting the trade-offs between simplicity, performance, and maintainability.
