Script Preparation code:

var dayjsNow = dayjs();
var luxonNow = luxon.DateTime.now();
var jsJodaNow = JSJoda.ZonedDateTime.now();
var now = new Date();

Tests:

Dayjs
dayjsNow.add(1, 'month');
luxon
luxonNow.plus({ months: 1 });
js-joda
jsJodaNow.plusMonths(1);
date-fns
dateFns.addMonths(now, 1);

**Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The provided JSON represents the benchmark, which tests four date manipulation libraries: dayjs, luxon, js-joda, and date-fns.

The test cases manipulate dates by adding one month to the current date using each library's respective function.

**Options Compared**

The options compared in this benchmark are:

* `dayjs`: adds one month to the current date using `add(1, 'month')`
* `luxon`: adds one month to the current date using `plus({ months: 1 })`
* `js-joda`: adds one month to the current date using `plusMonths(1)`
* `date-fns`: adds one month to the current date using `addMonths(now, 1)`

**Pros and Cons of Each Approach**

* **dayjs**: dayjs is a lightweight JavaScript library that provides a simple and intuitive API for date manipulation. However, it may not be as efficient as other libraries like luxon or js-joda, especially for more complex date calculations.
	+ Pros: easy to use, lightweight
	+ Cons: may not be as efficient
* **luxon**: luxon is a modern JavaScript library that provides a robust and efficient API for date manipulation. It is designed to handle complex date calculations with ease. However, it may have a steeper learning curve due to its feature-rich API.
	+ Pros: efficient, feature-rich API
	+ Cons: more complex API, larger footprint
* **js-joda**: js-joda is a JavaScript wrapper for the popular Joda-Time library. It provides a robust and efficient API for date manipulation, similar to luxon. However, it may not be as modern or lightweight as some other libraries.
	+ Pros: efficient, robust API
	+ Cons: less modern, larger footprint
* **date-fns**: date-fns is a lightweight JavaScript library that provides a simple and intuitive API for date manipulation. It is designed to be easy to use and efficient, but may not offer the same level of feature richness as other libraries.
	+ Pros: lightweight, easy to use
	+ Cons: less feature-rich

**Library Descriptions**

* **dayjs**: dayjs is a JavaScript library that provides a simple and intuitive API for date manipulation. It allows users to easily manipulate dates using methods like `add`, `subtract`, and `between`.
* **luxon**: luxon is a modern JavaScript library that provides a robust and efficient API for date manipulation. It includes features like support for different time zones, date formatting, and more.
* **js-joda**: js-joda is a JavaScript wrapper for the popular Joda-Time library. It provides a robust and efficient API for date manipulation, including support for various date formats and calculations.
* **date-fns**: date-fns is a lightweight JavaScript library that provides a simple and intuitive API for date manipulation. It includes methods like `addMonths`, `subtractYears`, and more.

**Special JS Features or Syntax**

The benchmark does not specifically test any special JavaScript features or syntax. However, it does rely on the use of various libraries and their respective APIs to perform date manipulations.

**Alternatives**

If you are looking for alternatives to these libraries, here are a few options:

* **Moment.js**: Moment.js is a popular JavaScript library for working with dates and times. It provides a simple and intuitive API for date manipulation.
* **Dateutil**: Dateutil is a lightweight JavaScript library that provides a simple and efficient API for date manipulation. It includes features like support for different time zones and date formatting.
* **Intl.DateTimeFormat**: Intl.DateTimeFormat is a modern JavaScript feature that allows users to format dates in a specific way. It can be used as an alternative to libraries like dayjs or luxon.

Overall, the choice of library depends on your specific use case and requirements. If you need a lightweight solution with a simple API, date-fns might be a good choice. If you need more features and efficiency, luxon or js-joda might be a better fit.
