Let's break down what's being tested in this benchmark.

**What's being compared?**

The test is comparing two approaches for finding the maximum value in an array: `Math.max.apply()` and the new ES6 spread operator (`...`).

**Options being compared:**

1. **`Math.max.apply(Math, arr)`**: This method uses the `apply()` function to call `Math.max` with the `arr` array as its first argument and `Math` as its second argument (the context). The result is passed back through the callback function.
2. **`Math.max(...arr)`**: This approach uses the spread operator (`...`) to pass the entire array to `Math.max`.

**Pros and cons of each approach:**

1. **`Math.max.apply(Math, arr)`**:
	* Pros:
		+ Works in older browsers that don't support the spread operator.
		+ Can be useful for legacy code or compatibility reasons.
	* Cons:
		+ Has a slightly higher overhead due to the `apply()` function call.
2. **`Math.max(...arr)`**:
	* Pros:
		+ More concise and readable than the `apply()` version.
		+ Optimized by modern browsers for performance.
	* Cons:
		+ May not work in older browsers that don't support the spread operator.

**Library usage:**

None of these benchmarks use a library.

**Special JS feature/syntax:**

The benchmark uses the ES6 spread operator (`...`). While this is a standard feature in modern JavaScript, it's still possible to encounter older browsers or environments that may not support it. MeasureThat.net takes care to test both approaches for compatibility.

**Other alternatives:**

Before `Math.max.apply()`, developers used various other methods to find the maximum value in an array, such as:

1. **`Math.max()` with multiple arguments**: This approach involves passing all elements of the array as separate arguments to `Math.max`. For example: `Math.max(...arr)`.
2. **Custom loops**: Before the spread operator was introduced, developers would use custom loops to find the maximum value in an array.

However, these alternatives are less efficient and more verbose than using `Math.max()` with either the spread operator or `apply()`.
