Benchmark: LoDash Omit vs Destructured undefined okay go

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js"></script>

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,
  darkRed,
  blue,
  lightBlue,
  navy
}

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'])
NAtive Spread and delete
const result = { ...basePalette }; delete result[orange]; delete result[red]; delete result[darkRed];

**Benchmark Definition**

The provided JSON represents a benchmark definition, which outlines the test cases to be executed. The main goal is to compare the performance of different approaches for removing or selecting properties from an object.

In this specific benchmark, we have four individual test cases:

1. **Native Destructure**: This approach uses the native JavaScript spread operator (`...`) and the `delete` keyword to remove properties from an object.
2. **LoDash Omit**: This approach utilizes the `_.omit` function from the LoDash library to remove specific keys from an object.
3. **LoDash Pick**: This approach uses the `_.pick` function from LoDash to select specific keys from an object and discard the rest.
4. **Native Spread and delete**: This approach also uses the native JavaScript spread operator (`...`) and the `delete` keyword, similar to Native Destructure.

**Options Compared**

The benchmark compares the performance of these four approaches:

* Native JavaScript features (Destructuring, `delete`, and Spread Operator)
* LoDash library functions (`_.omit` and `_.pick`)

**Pros and Cons of Each Approach**

1. **Native Destructure**: This approach has the potential to be faster since it leverages native JavaScript capabilities.
	* Pros: potentially faster, more intuitive syntax
	* Cons: may require explicit `delete` operations for each property, which can be verbose.
2. **LoDash Omit**: Using a library function provides a concise and readable way to remove properties from an object.
	* Pros: concise syntax, easy to read and maintain
	* Cons: relies on the LoDash library, which may introduce overhead.
3. **LoDash Pick**: Similar to `_.omit`, but selects specific keys instead of removing all others.
	* Pros: also concise and readable, allows for fine-grained control over selection
	* Cons: same drawback as `_.omit`: relies on the LoDash library.
4. **Native Spread and delete**: This approach is similar to Native Destructure but uses spread operator syntax (`{ ...obj }`) instead of object literal notation.
	* Pros: potentially faster, more concise syntax than Native Destructure
	* Cons: may require explicit `delete` operations for each property, which can be verbose.

**Library and Syntax**

The LoDash library is a popular utility belt for JavaScript that provides various functions for array manipulation, object transformation, and other tasks. The `_` character is used to prefix LoDash functions, so `_.omit` and `_.pick` are part of the LoDash API.

If test cases use some special JavaScript features or syntax (e.g., arrow functions, template literals), these would be explained in context. In this case, none are mentioned.

**Alternatives**

For those interested in exploring alternatives, other libraries like Lodash's competitors (e.g., Underscore.js) and custom implementations might offer varying trade-offs between performance, readability, and maintainability.

Some alternative approaches to consider:

* Using `Object.assign` with an empty object (`{}`) to remove properties from an object.
* Employing a more functional programming style using `filter` or `reduce`.
* Leveraging other libraries like Ramda for advanced data manipulation tasks.
