Learn the foundations of JavaScript functions in this vide. Discover what functions are, two ways to create them, and how to use them in your code.
Functions in programming are a way to reuse logic. They are the fundamental building block of logic in any programming language.
Functions allow you to reuse logic across your program easily.
A good function is one that is pure. What is a pure function you ask? A pure function is a function that returns the same value, if the inputs are the same. (like in the video).
When I was learning to code, I hadn't the faintest clue what functions were until I tried them for myself. Try them out using your code editor and tell me if you understand what functions are after this video!
