Keywords
Keywords are the strangest of the basic value types, they don’t have a real world analog like numbers, strings, or booleans.
For now you can think of them as a special type of string, but has super powers when used with maps.
:forename
:surname
:date-of-birth

Type a keyword into the REPL to see what is returned.
Ensure you start your keyword with a colon, :
:i-am-a-keyword
Hint
Keywords should make more sense when as we start looking at the map
