Functional programming is about writing code that is clean, predictable, and easier to test and debug. Two key concepts we'll explore today are pure functions and avoiding side effects.

Currying is a technique where we transform a function that takes multiple arguments into a sequence of functions, each taking a single argument.

What is recursion, and how does it work?
Let's learn how recursion works in JavaScript.
Recursion is a complicated feature that allows you to call a function repeatedly until a base-case is reached. Unlike a traditional loop, recursion allows you to handle something with an unknown depth, such as deeply nested objects/arrays, or a file tree. But you can also use it for more basic tasks, such as counting down from a given number.
Let’s construct a function to do exactly that. We’ll call our function recursiveCountdown, and it needs to accept a number. We’ll have it print this number to the console:
