Tests:

date with abs
var from = new Date(dsStart) var to = new Date(dsEnd) var res = Math.abs(from.getTime()-to.getTime()) < 60 * 6000
Momentjs
var from = moment(dsStart) var to = moment(dsEnd) var res = from.diff(to, 'seconds')
Dayjs
var from = moment(dsStart) var to = moment(dsEnd) var res = from.diff(to, 'seconds')
date without abs
var from = new Date(dsStart) var to = new Date(dsEnd) var res = from.getTime()-to.getTime()

Let's break down the provided JSON data and explain what's being tested.

**Benchmark Overview**

The benchmark compares the performance of three date formatting libraries: Moment.js, Day.js, and Date-fns. The test case measures the time taken to format two dates using each library.

**Library Descriptions**

1. **Moment.js**: A popular JavaScript date manipulation library that provides a wide range of features for working with dates.
2. **Day.js**: A lightweight and fast alternative to Moment.js, designed to be easier to use and more efficient.
3. **Date-fns**: A small, pure JavaScript library that provides a simple and functional API for working with dates.

**Test Cases**

The benchmark includes four test cases:

1. **"date with abs"`: Measures the time taken to calculate the absolute difference between two dates using `Math.abs()` (without formatting).
2. **"Momentjs"`: Measures the time taken to format two dates using Moment.js.
3. **"Dayjs"`: Measures the time taken to format two dates using Day.js.
4. **"date without abs"`: Similar to "date with abs", but without formatting.

**Options Compared**

Each test case compares a different approach:

1. Using `Math.abs()` (without formatting)
2. Using Moment.js
3. Using Day.js
4. Using Date-fns

**Pros and Cons of Each Approach**

Here's a brief summary:

* **"date with abs"`**: Simple, but may not accurately represent the performance of date formatting libraries.
	+ Pros: Easy to implement, quick results.
	+ Cons: May not reflect real-world use cases.
* **Moment.js**, **Day.js**, and **Date-fns**:
	+ Pros:
		- Fast execution times for date formatting tasks.
		- Well-documented APIs make it easier to write efficient code.
	+ Cons:
		- Steeper learning curve due to the need to understand the library's API and nuances.

**Special JS Features/Syntax**

None of the provided test cases use any special JavaScript features or syntax. The focus is on comparing the performance of different date formatting libraries.

**Alternatives**

If you're looking for alternative date formatting libraries, consider:

* **Lux**: A fast, modern JavaScript library for working with dates and times.
* **Moment-timezone**: An extension to Moment.js that adds support for timezones.
* **Date-fns-core**: The core library of Date-fns, providing a lightweight API for basic date operations.

Keep in mind that each library has its strengths and weaknesses, so it's essential to evaluate them based on your specific use case requirements.
