Benchmark: closure vs proto 3

Tests:

closure1
function MyFirstClass (one, two) { let _one = one; let _two = two; let _result = null; this.compute = function () { _result = _one * _two * _one * _two; } this.printResult = function () { console.log(_result); } } const mfc1 = new MyFirstClass(2, 9); mfc1.compute(); mfc1.printResult();
prototype1
function MyFirstProtoClass (one, two) { this._one = one; this._two = two; this._result = null; } MyFirstProtoClass.prototype.compute = function (){ this._result = this._one * this._two * this._one * this._two; }; MyFirstProtoClass.prototype.printResult = function (){ console.log(this._result); }; const mfpc1 = new MyFirstProtoClass(2, 9); mfpc1.compute(); mfpc1.printResult();

Let's break down the provided benchmark and explain what's being tested, compared, and analyzed.

**Benchmark Overview**

The benchmark compares two approaches to implement a simple class in JavaScript: using closures (also known as encapsulation or closure-based object creation) versus using prototypes (a built-in mechanism for creating objects that inherit properties from another object).

**Options Compared**

There are two options being compared:

1. **Closures (closure-based object creation)**: This approach uses functions to create new objects, which "remember" their own scope and variables through closure.
2. **Prototypes**: This approach uses the `prototype` property of objects to inherit properties from another object.

**Pros and Cons**

### Closures

Pros:

* Encapsulates data and behavior within a single function
* Provides a simple way to create new objects with their own state
* Can be more intuitive for small, self-contained objects

Cons:

* Can lead to tight coupling between objects, making them harder to reason about
* May result in slower performance due to the overhead of creating new function scopes

### Prototypes

Pros:

* Allows for loose coupling between objects, making it easier to maintain and extend code
* Can be more efficient than closures since there's no function scope creation overhead
* Provides a way to create object hierarchies with inheritance

Cons:

* Requires manual management of properties and methods using prototypes
* Can lead to complexity and confusion if not handled correctly

**Library Usage**

In the provided benchmark, no external libraries are used.

**Special JS Features/Syntax**

The benchmark uses JavaScript's function syntax and prototype property. Note that modern JavaScript versions (e.g., ECMAScript 2015+) provide additional features like classes, destructuring, and arrow functions, which are not present in this example.

**Other Alternatives**

If the developers wanted to explore alternative approaches, they could consider:

1. **Modules**: Using modules like ES6 imports/export or CommonJS require to manage dependencies and create objects.
2. **Class-based Object Creation**: Using modern JavaScript classes (introduced in ECMAScript 2015+) as an alternative to closures and prototypes.
3. **Object-Oriented Programming Frameworks**: Utilizing libraries like Lodash or other OOP frameworks that provide a higher-level abstraction for object creation and manipulation.

Keep in mind that the choice of approach depends on the specific requirements, performance constraints, and personal preference of the developers.
