Hello,
Total noobie here. I'm trying to create a sort of a string maker
function. Something like:
(defn string-maker [string-name the-string]
(def string-name (str the-string)))
so that I can call the function like so:
(string-maker friend Peter)
which I expect to give me the variable:

For what it's worth, Giancarlo makes a good (though vague) point when
recommending maps. You rarely (but not never!) want to def something
programmatically: defs are for things you as the programmer want to
give names to and have access to directly in source code. Often, this
