Benchmark: Date vs moment with compare

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.0/moment.min.js'></script>

Script Preparation code:

const date ='2021-11-23T12:00:00Z'
console.log('');

Tests:

moment
const date ='2021-11-23T12:00:00Z' const now = moment(); const isInFuture = moment(date) > now;
Date
const date ='2021-11-23T12:00:00Z' const now = new Date().getTime(); const isInFuture = new Date(date).getTime() > now;

Let's break down the provided benchmark definition and test cases to understand what is being tested.

**Benchmark Definition**

The JSON file defines two benchmarks: `Date vs moment with compare` and has a single script preparation code that sets a date variable `date`. The HTML preparation code includes a link to include the Moment.js library in the test environment.

**Script Preparation Code**

The script preparation code simply sets a JavaScript variable `date` to a specific date string using template literals. This code is executed before running each test case.

**HTML Preparation Code**

The HTML preparation code includes a script tag that loads the Moment.js library from a CDN. Moment.js is a popular JavaScript date and time manipulation library.

**Test Cases**

There are two individual test cases:

1. **moment**
   - The benchmark definition tests whether a given date (in this case, `date`) is in the future by comparing it with the current moment using the `moment()` function from the loaded Moment.js library.
   - This code uses the library's functionality to compare dates.

2. **Date**
   - The benchmark definition tests whether a given date (in this case, `date`) is in the future by converting it to milliseconds and comparing it with the current time using the `new Date()` function.

**Options Compared**

These two test cases are essentially comparing two different approaches for checking if a date is in the future:

- **Moment.js**: Uses Moment.js's built-in functions (`moment()`, `moment(date)`) to perform date comparisons.
- **Native JavaScript (Date)**: Utilizes native JavaScript methods (`new Date().getTime()`, `new Date(date).getTime()`).

**Pros and Cons of Each Approach**

1.  **Moment.js**:
    -   **Pros**: Moment.js is a well-maintained, widely-used library with robust functionality for date manipulation and comparisons.
    -   **Cons**: It includes an additional dependency (the JavaScript file) that may not be immediately apparent to users unfamiliar with libraries.
2.  **Native JavaScript (Date)**:
    -   **Pros**: No additional dependencies, making it a straightforward approach. The built-in `Date` object is native and thus easily recognizable to developers without needing library knowledge.
    **Cons**: May require more code and potentially less readable when dealing with complex date calculations.

**Library: Moment.js**

Moment.js is a powerful JavaScript library for working with dates and times in various formats. Its primary features include:

*   Date parsing and formatting
*   Arithmetic (addition, subtraction) on dates
*   Comparison of dates
*   Time zone handling

Its usage is widespread across web applications due to its simplicity and flexibility.

**Special JS Features/Syntax**

Neither test case explicitly utilizes any special JavaScript features or syntax. They purely focus on date comparison using native methods for one approach and the library's functions for another.
