1	Variables can have anything, you define them as equal to something

4    var statement = 'hello!'
5    var isAbool = true

7    there are three types of variables:
81. var 
92. let
103. const 
11
12var is a normal variable
13let is a variable whose value can be changed eg: let h = 12, h = 10(we changed the value, if you run this, there will be no error)
14const is a variable whose value cannot be changed, if you change the value of a const, you will have errors in you code
