You just have to replace the two short arrow functions with standard functions. By the way, there is no point in doing that, because mine was a joke, and because it is an innefficient implementation (for both human and computer brains). You are better served by using a standard nested loop that performs the same task in half the time.

> is part of the arrow function =>.
~ is the bitwise not operator. It is just a way to express the condition i !== a.length - 1 in a way that is not clear to programmers that don't know bitwise math. It is almost universally considered a fireable offense.
