Benchmark: es6 class static vs prototype

Script Preparation code:

const noop = () => {}

class Foo {
    static bar() {}

  	constructor () {
      this.bar2 = noop
    }
  
    bar() {}
}

var foo = new Foo()

Tests:

constructor
foo.constructor.bar()
prototype
foo.bar()
property
foo.bar2()

**Benchmark Explanation**

The provided JSON represents a JavaScript microbenchmark test case on the MeasureThat.net website. The benchmark tests three different approaches for calling a static method versus a property (or instance method) within a class in ECMAScript 6 (ES6).

**Approaches Compared**

1. **Static Method**: `foo.constructor.bar()`
2. **Property (Instance Method)**: `foo.bar()`
3. **Property (Direct Access)**: `foo.bar2()`

**Options Compared and Pros/Cons**

* **Static Method**: This approach uses the class's constructor as a proxy to call the static method `bar()`. The pros are that this approach can be faster since it avoids the overhead of creating an instance of the class. However, the cons are:
	+ Requires the use of the `new` keyword to create an instance of the class.
	+ May require additional memory allocation for the instance object.
* **Property (Instance Method)**: This approach accesses the property `bar2` directly on the instance object created by the constructor. The pros are that this approach:
	+ Does not require the use of the `new` keyword.
	+ Avoids additional memory allocation.
However, the cons are:
	+ May be slower due to the overhead of creating an instance object.
* **Property (Direct Access)**: This approach accesses the property `bar2` directly on the class without creating an instance. The pros are that this approach is often faster since it avoids the overhead of creating an instance object. However, the cons are:
	+ May not be supported by all browsers or environments.

**Library and Special Features**

The test case uses a JavaScript library (not explicitly stated) to create an instance of the class `Foo`. The library likely provides features such as:

* Class definition and instantiation
* Constructor function creation

There are no special JavaScript features or syntaxes used in this benchmark.

**Other Alternatives**

For similar benchmarks, you can explore other microbenchmarking frameworks and websites, such as:

* jsperf ( archived version available on Internet Archive)
* CodeOptimize
* JS-Bench
* Benchmark.js

These alternatives may offer different variations of the same benchmarks or new ones to compare.
