Benchmark: Bind vs Return Anonymous Function

Script Preparation code:

function bindFunction(bindedParam, param1, param2) {
	console.log(bindedParam, param1, param2)
}

function returnAnonFunction(bindedParam) {
	return (param1, param2) => {
		console.log(bindedParam, param1, param2)
    }
}

Tests:

Bind
bindFunction.bind(3)(1, 2)
Anonymous Function
returnAnonFunction(3)(1, 2)

Let's break down the benchmark and explain what's being tested, along with the pros and cons of each approach.

**Benchmark Definition**

The benchmark compares two approaches to invoking functions: `bind()` and returning an anonymous function.

**Bind vs Return Anonymous Function**

In JavaScript, `bind()` is a method that changes the context (or `this` value) of a function when it's invoked. In contrast, returning an anonymous function allows you to create a new scope for the function's execution.

**Options being compared:**

1. **Bind**: Invokes the function using `bind()`, which sets the first argument as the new `this` value.
2. **Return Anonymous Function**: Returns an anonymous function that takes two arguments, `param1` and `param2`.

**Pros and Cons of each approach:**

* **Bind**:
	+ Pros: More readable code, can be used with arrow functions (introduced in ES6).
	+ Cons: May introduce additional overhead due to the method call.
* **Return Anonymous Function**:
	+ Pros: No overhead introduced by `bind()`, can be more efficient.
	+ Cons: Less readable code, may not work well with some older browsers.

**Library usage**

There is no library explicitly mentioned in the benchmark definition. However, the use of `bind()` and arrow functions suggests that JavaScript version 9 or later is being used (since these features were introduced in ES6).

**Special JS feature/Syntax**

* **Arrow Functions**: Introduced in ES6, arrow functions provide a concise way to create small, one-time-use functions. They are similar to regular functions but use the `=>` operator instead of the `function` keyword.
* **Bind() method**: The `bind()` method is a built-in JavaScript method that changes the context (or `this` value) of a function when it's invoked.

**Other alternatives**

If you need to compare other approaches, some alternatives could be:

1. Using `call()` or `apply()` instead of `bind()`.
2. Creating an IIFE (Immediately Invoked Function Expression) instead of returning an anonymous function.
3. Using a library like Lodash to implement the binding functionality.

Keep in mind that these alternatives might not provide significant performance differences, and the benchmark may focus on readability, maintainability, or other factors over raw performance.
