Script Preparation code:

var basePalette = {
  black: undefined,
  green: null,
  orange: 'orange',
  red: null,
  darkRed: 'darkRed',
  blue: 'blue',
  lightBlue: 'lightBlue',

  blackOne: undefined,
  blackTwo: undefined,
  blackThree: undefined,
  blackFour: undefined,

}

Tests:

Plain Js
const isNullable = (obj) => obj == undefined || obj == null || (Array.isArray(obj) && obj.length < 1) const skipNullable = (obj) => { const temp = {} Object.keys(obj).forEach((key) => { if (isNullable(obj[key])) return temp[key] = obj[key] }) return temp } skipNullable(basePalette)
LoDash OmitBy
const isNullable = (v) => v == undefined || v == null || (Array.isArray(v) && v.length < 1) _.omitBy(basePalette, isNullable )

I'll explain what's being tested in the provided JSON, describe the options being compared, and discuss their pros and cons.

**What's being tested:**

MeasureThat.net is testing the performance of two approaches to remove null or undefined values from an object:

1. **Plain JavaScript**: This approach uses a custom function `isNullable` to check if a value is null, undefined, or has an empty array.
2. **LoDash OmitBy**: This approach uses the LoDash library's `omitBy` function to achieve the same result.

**Options being compared:**

The two options being tested are:

* Plain JavaScript (using a custom function)
* LoDash OmitBy (using the LoDash library)

**Pros and Cons of each approach:**

1. **Plain JavaScript**:
	* Pros:
		+ No external dependencies required
		+ Easy to understand and implement for developers familiar with JavaScript
	* Cons:
		+ May be slower due to the overhead of function calls and custom logic
		+ Requires more code to implement the `isNullable` function
2. **LoDash OmitBy**:
	* Pros:
		+ Faster execution speed (thanks to optimized native code)
		+ Less code required to achieve the same result
	* Cons:
		+ External dependency on LoDash library, which may not be suitable for all projects
		+ May require additional setup or configuration

**Library: LoDash**

LoDash is a popular JavaScript utility library that provides a collection of functional programming functions, including `omitBy`, which removes null or undefined values from an object. The library is widely used in the industry and offers performance benefits.

**Special JS feature/syntax: None mentioned**

There are no special JavaScript features or syntax being tested in this benchmark.

**Other alternatives:**

If you're interested in alternative approaches to remove null or undefined values from an object, some other options include:

* Using `Array.prototype.filter()` method to create a new array with only the non-null/undefined values
* Utilizing modern JavaScript features like optional chaining (`?.`) and the nullish coalescing operator (`??`)
* Leveraging libraries like Lodash (as shown in this benchmark) or other utility libraries that provide similar functionality.

These alternatives may offer trade-offs in terms of performance, code complexity, or external dependencies.
