Let's first talk about the building blocks of JavaScript, or

In JavaScript their are several data types, the most important being:
Strings, Numbers, Booleans, Arrays, and Objects
Variables are how values are stored.
They are decalred with the keyword 'var'
Let's make some variables with some data types!
