What is a Function?

What is a function?​

A function... what is a function? A function is a group or set of instructions that can be called anytime. A function is a great way to reuse code without actually writing it over and over again.

Disclaimer: the syntax below does not belong to any particular language, depending on the language it may be slightly different.

Example:​

Making eggs:
  1. Cracking an egg into a pan.
  2. Flip egg.
  3. Place on a plate.

Syntax:​

[CODE title="function syntax"]function makeEggs() {
add egg to pan
flip egg
place egg on plate
}[/CODE]

With this function, we can call by using makeEggs(); within our code and it will execute the code within the makeEggs function. Once code has been successfully been executed it will return after where the function was called.
