Let's break down what's being tested in the MeasureThat.net benchmark.

The benchmark compares two approaches to accessing nested properties in JavaScript:

1. **Lodash.get**: This is a utility function from the Lodash library, which helps with chaining method calls on objects. The `get` function takes an object and a path as arguments and returns the value at that path.
2. **Native Property Access**: This approach uses dot notation to access nested properties directly on the `person` object.

**What's being tested:**

The benchmark is testing which approach (Lodash.get or Native Property Access) performs better in terms of speed, specifically with longer paths (e.g., "name.something.else").

**Pros and Cons:**

* **Lodash.get**: Pros:
	+ Provides a concise and readable way to access nested properties.
	+ Can be useful when working with complex object structures.
* Cons:
	+ Requires including the Lodash library, which may add overhead.
	+ May not perform as well for very deep or large objects due to function call overhead.
* **Native Property Access**: Pros:
	+ No additional library required.
	+ Typically faster than using a library like Lodash for simple property access scenarios.
* Cons:
	+ Requires chaining multiple dot notation calls, which can make the code harder to read.

**Library Considerations:**

Lodash is a popular utility library that provides various functions for working with JavaScript objects. The `get` function is particularly useful when you need to dynamically access nested properties on an object.

**Special JS Feature/ Syntax:**

This benchmark does not use any special JavaScript features or syntax, such as async/await, generators, or ES6+ classes.

**Other Alternatives:**

If you don't want to use Lodash, you can also consider other alternatives for accessing nested properties in JavaScript, such as:

* Using a custom function with a loop to iterate through the object's property chain.
* Employing a recursive function to access deeply nested properties.
* Leveraging modern JavaScript features like `Object.prototype.hasOwnProperty.call` or `in` operator.

Keep in mind that these alternatives may have different performance characteristics compared to using Lodash or native property access.
