Exactly. '

is synonymous quote

, therefore

'[a b c]

just

(quote [a b c])

quote

prevents Clojure code from being evaluated, so quoting the entire vector is essentially the same as quoting every element of it:

['a 'b 'c]

It allows you to create a character vector without an explicit function call symbol

:

[(symbol "a") (symbol "b") (symbol "c")]
