Benchmark: LoDash Omit vs Destructured undefined vs real native

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
let oldPalette = basePalette; basePalette = { orange: undefined, red: undefined, darkRed: undefined, ...oldPalette };
LoDash Omit
_.omit(basePalette, ['orange','red', 'darkRed'])
LoDash Pick
_.pick(basePalette, ['blue', 'lightBlue', 'navy', 'black', 'green'])

Let's dive into the details of what's being tested on MeasureThat.net.

**Benchmark Definition**

The benchmark is testing three different approaches:

1. **Native Destructure**: This approach uses JavaScript's native destructuring feature to remove properties from an object. The test creates a new object `basePalette` and then modifies it by assigning `undefined` values to some of its properties, leaving the rest intact.
2. **LoDash Omit**: This approach uses LoDash's `omit` function to remove certain keys from an object. The test includes the LoDash library in the HTML preparation code.
3. **LoDash Pick**: This approach uses LoDash's `pick` function to extract specific properties from an object.

**Options Compared**

The three approaches are compared based on their performance, specifically the number of executions per second (ExecutionsPerSecond).

**Pros and Cons of Each Approach**

1. **Native Destructure**:
	* Pros: Native to JavaScript, potentially faster execution.
	* Cons: May not be supported in older browsers or environments.
2. **LoDash Omit**:
	* Pros: Widely supported library, easy to use.
	* Cons: Additional overhead due to the library's execution time.
3. **LoDash Pick**:
	* Pros: Similar to `omit`, but more straightforward to use.
	* Cons: Requires an additional dependency (the LoDash library).

**Library**

The LoDash library is a popular utility library for JavaScript, providing a set of functional programming functions that can be used in various contexts.

**Other Considerations**

In addition to performance, other factors like code readability and maintainability should also be considered when choosing an approach. For example, the native destructuring approach may require more complex code to handle edge cases, while LoDash's `pick` function provides a simpler, more straightforward solution.

**Special JS Feature or Syntax**

The benchmark uses JavaScript's native destructuring feature, which was introduced in ECMAScript 2015 (ES6). This syntax allows for concise and expressive way of removing properties from objects.

Overall, the benchmark provides a useful comparison of different approaches to object manipulation, highlighting the trade-offs between native JavaScript features, popular utility libraries like LoDash, and their performance characteristics.
