Script Preparation code:

window.__date__ = new Date();
window.__tz__ = 'America/Los_Angeles';
window.__moment_date__ = moment.tz(window.__date__, window.__tz__)
window.__luxon_date__ = luxon.DateTime.fromJSDate(window.__date__, {zone: window.__tz__})

Tests:

Moment add day
moment.tz(window.__date__, window.__tz__).add(10, 'day')
Luxon add day
luxon.DateTime.fromJSDate(window.__date__, {zone: window.__tz__}).plus({day: 10})
Moment add second
moment.tz(window.__date__, window.__tz__).add(1000, 'second')
Luxon add second
luxon.DateTime.fromJSDate(window.__date__, {zone: window.__tz__}).plus({second: 1000})
Luxon, add day, precreated date
window.__luxon_date__.plus({day: 100})
Moment, add day, precreated date
window.__moment_date__.add(100, 'day')

Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net!

**Benchmark Overview**

The benchmark compares the performance of two popular date and time libraries: Moment.js and Luxon. The tests measure the execution speed of various operations, such as adding days or seconds to a date object.

**Library Descriptions**

1. **Moment.js**: A widely-used JavaScript library for working with dates and times. It provides a simple and intuitive API for formatting, parsing, and manipulating dates.
2. **Luxon**: A modern and performant date and time library that aims to replace Moment.js. Luxon is designed to be more efficient and flexible than Moment.js.

**Options Compared**

The benchmark compares the performance of each library with different options:

* Adding days or seconds to a pre-created date object (`window.__date__`).
* Creating a new date object from scratch using `moment.tz()` or `luxon.DateTime.fromJSDate()`.
* Using different time zones (in this case, only `America/Los_Angeles` is used).

**Pros and Cons of Each Approach**

1. **Pre-created date object**: This approach is likely to be faster since it avoids the overhead of creating a new date object from scratch. However, it may not accurately represent real-world use cases where dates are generated dynamically.
2. **Creating a new date object**: This approach can provide more accurate results for certain use cases (e.g., when dates are generated dynamically). However, it may be slower than using a pre-created date object.
3. **Different time zones**: The benchmark only tests with one time zone, which may not accurately represent real-world scenarios where multiple time zones are used.

**Special JS Features or Syntax**

None of the tested code snippets use any special JavaScript features or syntax that would affect their performance. They rely solely on the library's built-in functionality to perform date and time operations.

**Other Alternatives**

If you're considering alternatives to Moment.js or Luxon, some popular options include:

1. **Date-fns**: A lightweight and efficient date and time library that provides a simple API for common operations.
2. **Dayjs**: A fast and feature-rich date and time library that aims to replace Moment.js.
3. **js-joda**: A JavaScript implementation of the Joda-Time library, which is widely used in Java-based applications.

Keep in mind that each library has its strengths and weaknesses, and the choice ultimately depends on your specific use case and requirements.
