Script Preparation code:

var black = 'black'
var green = 'green'
var orange = 'orange'
var red = 'red'
var darkRed = 'darkRed'
var blue = 'blue'
var lightBlue = 'lightBlue'
var navy = 'navy'

var basePalette = {
	black,
  green,
  orange,
  red,

}

Tests:

Native Destructure
var { orange: undefined, red: undefined, darkRed: undefined, ...coldPalette } = basePalette
LoDash Omit
_.omit(basePalette, ['orange','red', 'darkRed'])
LoDash Pick
_.pick(basePalette, ['blue', 'lightBlue', 'navy', 'black', 'green'])

**What is being tested?**

The provided benchmark tests the performance of three different approaches:

1. **Native Destructure**: This approach uses JavaScript's built-in destructuring feature to create an object with only the desired properties from `basePalette`. The object is created by assigning the desired properties directly to new variables, e.g., `var { orange: undefined, red: undefined, darkRed: undefined, ...coldPalette } = basePalette;`.
2. **LoDash Omit**: This approach uses Lodash's `omit` function to create a new object that excludes the specified properties from `basePalette`. The function takes an object as input and returns a new object with the desired properties removed.
3. **LoDash Pick**: This approach uses Lodash's `pick` function to create a new object that includes only the specified properties from `basePalette`.

**Options compared**

The benchmark compares the performance of these three approaches:

* Native Destructure vs LoDash Omit
* Native Destructure vs LoDash Pick
* LoDash Omit vs LoDash Pick

**Pros and Cons of each approach:**

1. **Native Destructure**
	* Pros:
		+ Efficient, as it only creates a new object with the desired properties.
		+ Uses built-in JavaScript features, which can be faster than library functions.
	* Cons:
		+ Can be less readable due to its concise syntax.
2. **LoDash Omit**
	* Pros:
		+ Highly readable and maintainable code, as it uses a clear and explicit function name.
		+ Allows for easy addition of new properties to omit in the future.
	* Cons:
		+ Requires an additional library (Lodash) to be included.
		+ Can be slower due to the overhead of calling a library function.
3. **LoDash Pick**
	* Pros:
		+ Highly readable and maintainable code, as it uses a clear and explicit function name.
		+ Allows for easy addition of new properties to pick in the future.
	* Cons:
		+ Requires an additional library (Lodash) to be included.
		+ Can be slower due to the overhead of calling a library function.

**Library usage**

The benchmark uses Lodash, which is a popular JavaScript utility library that provides a set of functions for common tasks, including object manipulation. The `omit` and `pick` functions are used to filter objects by excluding or including specific properties, respectively.

**Special JS feature/Syntax**

There is no special JavaScript feature or syntax used in this benchmark, only standard JavaScript features like destructuring and array methods (e.g., `_.omit`, `_.pick`).
