Benchmark: Math.max/min vs if vs ternary - 3 numbers

Script Preparation code:

var x = Math.random() * 1000;
var clientX = Math.random() * 1000;
var px = Math.random() * 1000;
var maxWidth = Math.random() * 1000;

Tests:

Math.max/min
Math.min(Math.max(x + clientX - px, 0), maxWidth) - x
if
if(x + clientX - px < 0) return 0; if(x + clientX - px > 750) return maxWidth; return x + clientX - px;
ternary
return x + clientX - px < 0 ? 0 : (x + clientX - px > maxWidth ? maxWidth : x + clientX - px) - x;

Let's dive into the explanation of the provided benchmark.

**What is tested:**

The benchmark measures the performance difference between three different approaches to find the minimum value among three numbers:

1. `Math.min` and its counterpart `Math.max`
2. An `if-else` statement
3. A ternary operator

These approaches are compared on a single test case, where three random numbers (`x`, `clientX`, and `px`) are generated.

**Options compared:**

* **Math.min/Math.max**: This is the built-in JavaScript function to find the minimum or maximum value in an array.
* **If-else statement**: A conditional statement that checks if a condition is true, and executes one code block if it's true, and another code block if it's false. In this case, the condition checks if `x + clientX - px` is less than 0 or greater than 750.
* **Ternary operator**: A shorthand way to write an if-else statement in a single expression.

**Pros and cons of each approach:**

1. **Math.min/Math.max**:
	* Pros: Fast, reliable, and widely supported.
	* Cons: May not be suitable for all use cases (e.g., finding the maximum value in a small array).
2. **If-else statement**:
	* Pros: Easy to understand and implement, can handle complex conditions.
	* Cons: Can lead to slower performance due to the overhead of the conditional checks.
3. **Ternary operator**:
	* Pros: Compact and readable, suitable for simple cases like this one.
	* Cons: May be less efficient than the if-else approach for more complex conditions.

**Library usage:**

None of the provided benchmark scripts use any external libraries.

**Special JS feature or syntax:**

The only special syntax used is the ternary operator (`?:`), which is a shorthand way to write an if-else statement in a single expression. The `if-else` statement and `Math.min/Math.max` functions do not use any special syntax.

**Benchmark preparation code:**

The script prepares three random numbers (`x`, `clientX`, and `px`) for the benchmark using the following lines:
```javascript
var x = Math.random() * 1000;
var clientX = Math.random() * 1000;
var px = Math.random() * 1000;
```
**Other alternatives:**

Some alternative approaches to finding the minimum value among three numbers could include:

* Using a custom function or algorithm
* Utilizing other mathematical functions, such as `Math.min` with an array of values
* Employing parallel processing or multi-threading to speed up the computation

However, these alternatives are not included in the provided benchmark.
