Avoid confusing prototype methods for static methods

Correct: `Array.from()` (it’s a static method)
Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method)

This patch uses the common `#` syntax to denote `.prototype.`.

 ### binarySearch
 
-Use recursion. Similar to `Array.indexOf()` that finds the index of a value within an array.
-The difference being this operation only works with sorted arrays which offers a major performance boost due to it's logarithmic nature when compared to a linear search or `Array.indexOf()`.

 Search a sorted array by repeatedly dividing the search interval in half.
 Begin with an interval covering the whole array.
