Special words that the mean something to the programming language.
Keywords tend to be used with something else.
Languages have there own keywords, some common keyword:
- var X: Create a new Variable called X.
- return X: Return X.
- function X: Create a new Function called X.

Operand	Operator	Operand	Meaning
2	+	2	2 plus 2
message	=	`"Hello"`	Assign to a variable
Count	++		Increase a variable by 1

Functions are a way of organising code.
- We can pass data into functions.
Code is grouped together inside a Code Block.
- A Code Block is Code surrounded by Curly Brackets { }.
- We call this the Function Body.

function X() {
  return "Hello";
}
Or...
var x = () => "Hello";

function greet(name) { return "Hello " + name; }
greet("Luke");
