A function is like a vraiable in the fact of that they both work coherently

Fucntions can be helpful in breaking down big prolblems as you can assign them a specific value, which helps save time and helps make the code less clunky and long.
A variable is used for a short hand of a value for example a variable could be X and X could be defined as something like (hello) which would then shape into a bigger code if ever need be repeated.
