Functions in Coding

A function is a named set of instructions that can be reused. Functions make code shorter, easier to read and easier to fix.

Instead of writing the same steps many times, you write them once inside a function and call it by its name whenever you need it. Functions can also take in information and give back a result.

If a game needs to draw a star in many places, one function called draw star can do the job each time. Breaking a big program into functions also makes it easier to find and fix mistakes.
