Benchmark: Math.max/min vs if vs ternary operator #2

Script Preparation code:

var number = Math.random() * 1000;

Tests:

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

**Benchmark Overview**

The provided benchmark compares the performance of three different approaches to find the maximum or minimum value between two numbers: using `if` statements, ternary operators (`ternary`), and `Math.max()`/`Math.min()` functions.

**Approaches Compared**

1. **If Statements**: This approach uses an `if-else` statement to check if the input number is less than 250 or greater than 750, and returns either 250 or 750 accordingly.
2. **Ternary Operator (ternary)**: This approach uses a ternary operator to concisely express the same logic as the `if` statements, with three conditions that evaluate to different values based on the input number.
3. **Math.max() / Math.min() Functions**: This approach uses built-in JavaScript functions to find the maximum or minimum value between two numbers.

**Pros and Cons of Each Approach**

1. **If Statements**
	* Pros: Easy to understand, readable code.
	* Cons: May lead to longer execution times due to the overhead of conditional checks.
2. **Ternary Operator (ternary)**
	* Pros: Concise, efficient code that can be faster than `if` statements.
	* Cons: May require additional mental effort to understand and maintain.
3. **Math.max() / Math.min() Functions**
	* Pros: Built-in functions are optimized for performance and provide a concise way to solve the problem.
	* Cons: Requires knowledge of built-in functions, which may not be familiar to all developers.

**Library Used**

None.

**Special JS Features or Syntax**

None mentioned in the benchmark definition.

**Benchmark Preparation Code Explanation**

The preparation code `var number = Math.random() * 1000;` generates a random integer value between 0 and 1000 for each test case, which is used to evaluate the performance of each approach.

**Other Alternatives**

1. **Using `Math.max()`/`Math.min()` with two arguments**: This approach uses both functions to find the maximum or minimum value between two numbers in a single statement. For example: `return Math.max(number, 250);`
2. **Using bitwise operations**: This approach uses bitwise operators to find the maximum or minimum value between two numbers without using built-in functions. For example: `(number + 750) > number ? 750 : number`

Note that these alternative approaches are not included in the provided benchmark definition and would require additional test cases to measure their performance.
