Benchmark: Mathjs evaluation

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjs/12.2.0/math.min.js"></script>

Script Preparation code:

var func1 = (x, y, z) => x*x + y*y + z*z;
var expr2 = math.parse('x^2 + y^2 + z^2').compile()
var func2 = (x, y, z) => expr2.evaluate({x, y, z})

Tests:

Native
const out = [] for (let x = 0; x < 100; x += 1) { for (let y = 0; y < 100; y += 1) { for (let z = 0; z < 100; z += 1) { out.push(func1(x, y, z)) } } }
Mathjs compile
const out = [] for (let x = 0; x < 100; x += 1) { for (let y = 0; y < 100; y += 1) { for (let z = 0; z < 100; z += 1) { out.push(func2(x, y, z)) } } }

**Benchmark Overview**

MeasureThat.net is a platform that allows users to create and run JavaScript microbenchmarks. The provided benchmark measures the performance of two approaches: native (without any library or compilation) and Mathjs-compiled (using the Mathjs library).

**Native Approach**

The native approach tests the execution speed of the `func1` function, which is a simple polynomial expression evaluated using basic arithmetic operations.

**Pros and Cons:**

* Pros:
	+ Simple to implement and understand.
	+ No additional dependencies or compilation required.
* Cons:
	+ May not be as efficient as other approaches due to the overhead of JavaScript's interpreter and engine.

**Mathjs-Compiled Approach**

The Mathjs-compiled approach uses the Mathjs library to compile the expression into a native machine code, which is then executed.

* Pros:
	+ Can be faster than the native approach due to compilation.
	+ Provides better performance for complex expressions.
* Cons:
	+ Requires an additional dependency (Mathjs) and compilation step.
	+ May introduce overhead due to library initialization and runtime checks.

**Mathjs Library**

The Mathjs library is a JavaScript implementation of mathematical functions, allowing developers to compile expressions into native machine code using the Just-In-Time (JIT) compiler. The library provides various benefits, including:

* Faster execution speeds for complex calculations.
* Reduced memory usage due to efficient data representation and caching.
* Simplified development and debugging with built-in utilities.

**Special JavaScript Feature:**

This benchmark does not utilize any special JavaScript features or syntax that may impact performance, such as async/await, promises, or modern web APIs.

**Other Alternatives:**

Other alternatives for benchmarking JavaScript performance include:

1. **Babel**: A transpiler that converts ES6+ code to older JavaScript versions.
2. **V8.js**: A JavaScript engine that provides a similar API to the V8 engine used by Google Chrome.
3. **SpiderMonkey**: A JavaScript engine developed by Mozilla, often used in benchmarking and performance testing.
4. **Emscripten**: A compiler that translates C/C++ code to WebAssembly (WASM), allowing for cross-compilation and efficient execution.

Keep in mind that each alternative has its strengths and weaknesses, and the choice of which one to use depends on specific requirements and goals.
