Let's dive into the world of JavaScript microbenchmarks!

**What is being tested?**

MeasureThat.net is testing various libraries that provide support for decimal arithmetic, specifically:

1. `bignumber.js`: A library for high-precision floating-point numbers.
2. `big.js`: A library that provides support for decimal arithmetic with a focus on simplicity and ease of use.
3. `decimal.js`: A widely-used library for working with decimal numbers in JavaScript.
4. `Fraction.js` (without native): A library for working with rational numbers.

**Options compared**

The tests compare the performance of each library when performing basic arithmetic operations, such as addition, multiplication, and concatenation, on two decimal numbers:

* `var a = new Decimal("0.1"); var b = new Decimal("0.2");`
* `var a = new Big("0.1"); var b = new Big("0.2");`
* `var a = new BigNumber("0.1"); var b = new BigNumber("0.2");`
* `var a = new BigDecimal("0.1"); var b = new BigDecimal("0.2");`
* `var a = new Fraction("0.1"); var b = new Fraction("0.2");`

**Pros and cons of each approach**

Here's a brief summary of the pros and cons of each library:

1. **bignumber.js**:
	* Pros: High precision, fast execution.
	* Cons: Steeper learning curve due to advanced features.
2. **big.js**:
	* Pros: Simple and intuitive API, good performance.
	* Cons: May not be suitable for high-precision arithmetic.
3. **decimal.js**:
	* Pros: Wide adoption, stable API, good performance.
	* Cons: May have limitations in precision or speed for very large numbers.
4. **Fraction.js** (without native):
	* Pros: Lightweight, easy to use, suitable for rational numbers.
	* Cons: Limited support for decimal arithmetic.

**Special JS features**

None of the libraries mentioned in the benchmark require any special JavaScript features or syntax beyond standard arithmetic operations.

**Other alternatives**

If you're looking for alternative libraries that provide similar functionality, consider:

1. **big-integer.js**: A library for high-precision integer arithmetic.
2. **js-math**: A comprehensive mathematics library with support for decimal arithmetic.
3. **decimal-arithmetic**: A lightweight library for decimal arithmetic.

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

I hope this explanation helps you understand what's being tested in MeasureThat.net!
