Script Preparation code:

var obj = { car: { honda: { tyres: { tread: '3mm' } } } };

Tests:

Multiple Lodash get
const selectCar = (obj) => _.get(obj, 'car', {}); const selectHonda = (obj) => _.get(selectCar(obj), 'honda', {}); const selectTyres = (obj) => _.get(selectHonda(obj), 'tyres', {}); _.get(selectTyres(obj), 'tread', '5mm');
Single Lodash get
_.get(obj, 'car.honda.tyres.tread', '5mm');
Native
obj.car.honda.tyres.tread

Let's break down the provided benchmark definition and test cases.

**What is tested:**

The benchmark measures the performance of accessing nested properties in JavaScript objects, specifically using two approaches:

1. **Multiple Lodash.get**: This approach uses the `_.get()` function from the Lodash library to access nested properties. The function takes three arguments: the object, the property path, and a default value.
2. **Single Lodash.get**: This approach uses the same `_.get()` function but with only two arguments: the object and the property path.
3. **Native**: This approach accesses the nested property directly without using any additional functions or libraries.

**Options compared:**

The benchmark compares the performance of these three approaches:

* Multiple Lodash.get: A safe, explicit way to access nested properties using a function that handles errors and provides a default value.
* Single Lodash.get: A more concise way to access nested properties but without error handling or default values.
* Native: The most direct way to access nested properties, which may be faster but also more prone to errors.

**Pros and Cons of each approach:**

1. **Multiple Lodash.get**:
	* Pros:
		+ Safe and explicit way to access nested properties
		+ Handles errors and provides default values
	* Cons:
		+ Adds an extra function call, which may incur overhead
2. **Single Lodash.get**:
	* Pros:
		+ More concise and easier to read
	* Cons:
		+ No error handling or default values, which may lead to errors or unexpected behavior
3. **Native**:
	* Pros:
		+ Fastest way to access nested properties (no function calls)
	* Cons:
		+ Most prone to errors due to lack of error handling and default values

**Lodash library:**

The Lodash library is a popular JavaScript utility library that provides a wide range of functions for tasks such as:

* String manipulation
* Array manipulation
* Object manipulation (e.g., _.get(), _.set())
* Function manipulation (e.g., _.partial())

In this benchmark, the `_.get()` function is used to access nested properties in an object.

**Special JS feature or syntax:**

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

Now, let's look at the individual test cases:

1. **Multiple Lodash.get**: This test case uses three calls to `_get()` with different property paths.
2. **Single Lodash.get**: This test case uses only one call to `_get()` with a single property path.
3. **Native**: This test case accesses the nested property directly without using any additional functions or libraries.

**Other alternatives:**

There are other ways to access nested properties in JavaScript, such as:

* Using bracket notation (`obj['car']['honda']['tyres']['tread']`)
* Using dot notation (`obj.car.honda.tyres.tread`)
* Using a recursive function to traverse the object tree

However, these alternatives may not provide the same level of safety and explicitness as using `_.get()` or accessing nested properties directly.
