Boolean

Booleans basically answer any questions with yes or no, or more emphatically, True or False.

Three data types now:

let age = 20
let name = "Alex"
let canVote = true

• Booleans can be seen as answers to yes/no questions.
• There are only 2 boolean values: true and false.
• You should NOT wrap true and false with quotes. Only do that for strings.
