• Functions

    A function in programming is a task you the program to perform. It tells the computer what to do and how to do it when it runs a certain program. It's kind of like telling a robot what to do. For example, if you want the robot to make something for you, you would give it instructions or write down a recipe on how to make that thing. That's what functions are like: instructions for the computer on how to make something happen.
