Functional Programming

Let's get a taste of Functional Programming.

Iteration vs. Recursion

Recursion and iteration are related. They both are ways to repeat code with a slighty different context.

Change the code below so it uses recursion to call uploadFile on each file without mutating any variables.

Restrictions: No mutable values (let, var, for, while, etc) or built-in array methods (map, filter, etc)
