I am reading through Realm of Racket and saw this function in the conditions
chapter:
(if (= (+ 1 2) 3)
'yup
'nope)
So this function returns a symbol. Will be 'yup in above case. But 'yup
confuses me. I don't really understand why you would want to return 'yup.
For example, I could re-write the function like this:
(if (= (+ 1 2) 3)
"yup"
"nope")
which now returns a string. This is more understandable, it is simpler.
Why would you want to write a function like the first one which returns 'yup?
