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.
