Working with lists

Missing quote

Error Message

ClassCastException java.lang.String cannot be cast to clojure.lang.IFn

Cause

The above error can occur when we try to create a list literal without the quote:

("a" "b" "c")

Solutions

Either add the initial single quote:

'("a" "b" "c")

or use the list function:

(list "a" "b" "c")
