Benchmark: World's Fasted Min Max

Script Preparation code:

function minmax1 (value) {
  return value < 0 ? 0 : value > 255 ? 255 : value
}

function minmax2 (value) {
  if (value < 0) {
    return 0
  } else if (value > 255) {
    return 255
  }
  return value
}

function minmax3 (value) {
  return Math.min(Math.max(value, 0), 255)
}

Tests:

ternary
minmax1(-123);minmax1(123);minmax1(123123);
if else
minmax2(-123);minmax2(123);minmax2(123123);
math min/max
minmax3(-123);minmax3(123);minmax3(123123);

I'll break down the benchmark and its options for you.

**Benchmark Definition**

The provided JSON represents a JavaScript microbenchmark, which is a small piece of code designed to measure the performance of specific parts of the language or libraries. In this case, we have three separate benchmarks: `minmax1`, `minmax2`, and `minmax3`.

Each benchmark defines a function that takes an input value and returns a processed value. The functions differ in their implementation:

1. `minmax1` uses a ternary operator to check if the value is less than 0, and if so, returns 0. If the value is greater than 255, it returns 255. Otherwise, it returns the original value.
2. `minmax2` uses an `if-else` statement to achieve the same result as `minmax1`.
3. `minmax3` uses the `Math.min` and `Math.max` functions to process the input value.

**Options Compared**

The three benchmarks compare different approaches to achieve the same result:

* Ternary operator (`minmax1`) vs. `if-else` statement (`minmax2`)
* Use of `Math.min` and `Math.max` functions (`minmax3`) vs. simple conditional checks (`minmax1` and `minmax2`)

**Pros and Cons**

Here are some pros and cons of each approach:

1. Ternary operator (`minmax1`):
	* Pros: concise, easy to read, and often faster due to its optimization by the compiler.
	* Cons: may not be as readable for complex conditions, and can lead to unexpected behavior if not used correctly.
2. `if-else` statement (`minmax2`):
	* Pros: more explicit and readable than ternary operators, especially for complex conditions.
	* Cons: generally slower than ternary operators due to the overhead of conditional checks.
3. Use of `Math.min` and `Math.max` functions (`minmax3`):
	* Pros: concise and easy to read, as well as often faster due to the optimization provided by the JavaScript engine.
	* Cons: may not be supported by older browsers or environments that don't have these functions.

**Libraries and Special Features**

None of the benchmarks use any libraries specifically. The `Math.min` and `Math.max` functions are part of the standard JavaScript library, which is included with most modern browsers.

**Special JS Features**

There are no special features used in this benchmark, such as async/await or generators.

**Other Alternatives**

Some other alternatives to these approaches could be:

* Using a library like Lodash's `min` and `max` functions
* Implementing a custom min-max function using bitwise operations (e.g., `minmax1`)
* Using a more complex approach, such as using a binary search algorithm to find the minimum or maximum value

However, these alternatives would likely add complexity and overhead to the benchmark, making it less suitable for measuring performance.
