Day 029 - Boolean

Simply put a boolean returns either a true or false value.

You'll find it very handy if you want to action code dependent on whether a value is true or false.

For example if you had a site where users could log in, you could write some conditional code to check if the user was logged in.

If the statement came back true you could display their name, if it came back false, you could prompt them to log in or sign up.
