Benchmark: min and max - MeasureThat.net

Script Preparation code:

function mathFns(x, y, a, b) {
    const x0 = Math.min(x, a)
    const x1 = Math.max(x, a)
    const y0 = Math.max(y, b)
    const y1 = Math.max(y, b)
    return [x0, y0, x1, y1]
}

function sorted(x, y, a, b) {
    const [x0, x1] = [x, a].sort((p, q) => p - q)
    const [y0, y1] = [y, b].sort((p, q) => p - q)
    return [x0, y0, x1, y1]
}


function ifElse(x, y, a, b) {
  	let x0, y0, x1, y1
    if (x < a) {
      x0 = x
      x1 = a
    } else {
      x0 = a
      x1 = x
    }
  
  	if (y < b) {
      x0 = y
      x1 = b
    } else {
      x0 = b
      x1 = y
    }
  
    return [x0, y0, x1, y1]
}


function ternary(x, y, a, b) {
  	let x0, y0, x1, y1
    x0 = Math.min(x, a)
    x1 = x0 === a ? x : a
    y0 = Math.min(y, b)
    y1 = y0 === b ? y : b
  
    return [x0, y0, x1, y1]

Let's break down the benchmark and explain what is being tested.

**Benchmark Definition**

The provided JSON represents a set of JavaScript microbenchmarks defined in a single file. The benchmarks are:

1. `mathFns(x, y, a, b)`: This function calculates the minimum and maximum values between two sets of numbers.
2. `sorted(x, y, a, b)`: This function returns the smallest and largest values from two sets of numbers after sorting them.
3. `ifElse(x, y, a, b)`: This function uses an if-else statement to determine the minimum and maximum values between two sets of numbers.
4. `ternary(x, y, a, b)`: This function uses a ternary operator to calculate the minimum and maximum values between two sets of numbers.

**Options Compared**

Each benchmark compares different approaches to calculating the minimum and maximum values:

* `mathFns` uses a straightforward approach with multiple lines of code.
* `sorted` uses sorting algorithms (specifically, the built-in `sort()` method) to find the smallest and largest values.
* `ifElse` uses an if-else statement to determine the minimum and maximum values.
* `ternary` uses a ternary operator to calculate the minimum and maximum values.

**Pros and Cons of Each Approach**

Here's a brief analysis of each approach:

1. **mathFns**: Pros - straightforward, easy to read; Cons - may be slower due to multiple lines of code.
2. **sorted**: Pros - efficient, scalable; Cons - requires sorting algorithm, which can be slow for large datasets.
3. **ifElse**: Pros - simple, easy to understand; Cons - may be slower due to the if-else statement.
4. **ternary**: Pros - concise, easy to read; Cons - may not be as efficient as other approaches.

**Library Used**

None of the provided benchmarks use any external libraries or frameworks. They rely solely on built-in JavaScript functionality.

**Special JS Features/Syntax**

There are no special JavaScript features or syntax used in these benchmarks, such as `let`, `const`, or arrow functions.

**Other Alternatives**

If you were to reimplement these benchmarks using alternative approaches, some options might include:

1. **Functional programming**: Instead of using loops and conditionals, you could use higher-order functions like `reduce()` or `map()` to calculate the minimum and maximum values.
2. **Template literals**: You could use template literals to create strings that represent the minimum and maximum values, instead of concatenating strings with `+`.
3. **BigInts**: If available, you could use BigInts to handle larger integer values without losing precision.

Keep in mind that these alternatives would require changes to the benchmark code and may not directly compare to the original implementations.

In summary, these benchmarks provide a simple yet effective way to compare different approaches to calculating minimum and maximum values in JavaScript. By examining the pros and cons of each approach, developers can make informed decisions about which method is best suited for their specific use case.
