## Functions
At its core, a function is a block of code we can execute on demand. This is perfect for scenarios where we need to perform the same task multiple times; rather than duplicating the logic in multiple locations (which would make it hard to update when the time comes), we can centralize it in one location, and call it whenever we need the operation performed - you can even call functions from other functions!.
