Tests:

moment/luxon
var actual = luxon.DateTime.fromISO("2017-05-15").plus({days: 1}).toString(); console.assert(actual === __expected__);
moment/moment
var actual = moment("2017-05-15").clone().add(1, 'd').toISOString(); console.assert(actual === __expected__);
js-joda
var actual = JSJoda.LocalDate.parse("2017-05-15").plusDays(1).format(JSJoda.DateTimeFormatter.ISO_LOCAL_DATE); console.assert(actual === __expected__);

Let's break down the provided benchmark and its components.

**Benchmark Overview**

MeasureThat.net is a website where users can create and run JavaScript microbenchmarks to compare the performance of different libraries or implementations. In this case, we have three benchmark definitions that test the formatting capabilities of three date libraries: moment.js, luxon.js, and js-joda.

**Library Descriptions and Purposes**

1. **moment.js**: Moment is a popular JavaScript date library that provides an easy-to-use API for working with dates. It's known for its simplicity and flexibility. In this benchmark, it's used to test the formatting of dates.
2. **luxon.js**: Luxon is another modern JavaScript date library that aims to provide a more efficient and expressive API than moment.js. It's designed to be faster and more flexible, with features like ISO 8601 parsing and formatting.
3. **js-joda**: Js-joda is a JavaScript implementation of the Joda-Time library, which is a widely used Java date library. Js-joda provides an efficient way to work with dates in JavaScript.

**Test Cases**

The benchmark consists of three test cases:

1. `moment/luxon format`: This test case uses luxon.js to format a date string.
	* **Pros**: Luxon's ISO 8601 parsing and formatting capabilities are likely to be faster than moment.js, given its more efficient implementation.
	* **Cons**: The benchmark may not accurately represent real-world usage scenarios, as it only tests formatting and doesn't account for more complex date operations.
2. `moment/moment`: This test case uses moment.js to format a date string.
	* **Pros**: Moment is widely used and well-established, making its performance more predictable in this context.
	* **Cons**: As mentioned earlier, the benchmark may not accurately represent real-world usage scenarios.
3. `js-joda`: This test case uses js-joda to format a date string.
	* **Pros**: Js-joda's implementation is designed for JavaScript and may provide better performance than moment.js or luxon.js in this specific context.
	* **Cons**: The benchmark may not accurately represent real-world usage scenarios, as it only tests formatting.

**Special JS Feature:**

There is no explicit mention of any special JavaScript features or syntax being used in these benchmarks. However, the use of `console.assert` suggests that the benchmark is written for debugging purposes and may not be optimized for production use.

**Other Alternatives:**

If you're interested in comparing the performance of other date libraries, some alternatives to consider include:

* Date-fns: A lightweight JavaScript library for working with dates.
* Day.js: A modern JavaScript date library that aims to provide a more efficient API than moment.js.
* Date-parser: A lightweight JavaScript library specifically designed for parsing and formatting dates.

Keep in mind that the choice of library ultimately depends on your specific use case, performance requirements, and personal preference.
