Benchmark: Math.max/min vs if vs ternary(non-nested) operator

Script Preparation code:

this.number = Math.random() * 1000;

Tests:

Math.max/min
return Math.max(250, Math.min(750, this.number));
if
var number = this.number; if(number < 250) return 250; if(number > 750) return 750; return number;
ternary
var number = this.number; number = number < 250 ? 250 : number; number = number > 750 ? 750 : number; return number;

**Benchmark Definition and Options**

The benchmark defines three different ways to achieve the same result: finding the maximum or minimum value between 250 and 750, where the input value is stored in `this.number`. The options being compared are:

1. **Math.max/min**: Using the built-in `Math.max` and `Math.min` functions.
2. **if-else statements**: Using a simple if-else chain to compare the input value with 250 and 750.
3. **ternary operator (non-nested)**: Using a single ternary operator (`?:`) to concisely express the same logic.

**Pros and Cons of Each Approach**

* **Math.max/min**:
	+ Pros: Concise, efficient, and widely supported.
	+ Cons: May not be as easy to understand for beginners or those unfamiliar with this syntax.
* **if-else statements**:
	+ Pros: Easy to understand, flexible, and adaptable to complex logic.
	+ Cons: Can be verbose, slower due to the overhead of branching.
* **ternary operator (non-nested)**:
	+ Pros: Concise, efficient, and can be faster than if-else for simple cases.
	+ Cons: May not be as easy to understand for beginners or those unfamiliar with this syntax. Limited flexibility.

**Library Used**

There is no explicitly mentioned library in the benchmark definition. However, it's worth noting that the `Math` object is a built-in JavaScript library, and its functions are widely supported across most browsers and environments.

**Special JS Features or Syntax**

The benchmark uses the ternary operator (`?:`) with a single expression, which is a feature introduced in ECMAScript 2010 (ES5). This syntax allows for concise expressions that combine multiple conditions and return values.

**Other Alternatives**

If you'd like to explore alternative approaches, consider the following:

* Using `Math.max` or `Math.min` functions with a different comparison order (e.g., using `>=` instead of `<`).
* Implementing your own custom min/max function using JavaScript's built-in arithmetic operations.
* Utilizing bitwise operators or other clever tricks to optimize performance.

Keep in mind that these alternatives might not be supported by all browsers or environments, and may require additional effort to implement and maintain.
