; Conditions are fairly typical: (const answer 42) (if (= answer 42) (prn :simple :boom) (prn :simple :no-dice)) ; Conditions are hoisted and can be used as expressions: (prn :hoisted (if (= answer 42) :boom)) ; Every pair is a condition, the last lone clause is the else. (prn :multiple (if (< answer 42) :too-low (> answer 42) :too-high (= answer 42) :just-right)) ; Prefer `when` for single condition without else clause: (when (= answer 42) (prn :when answer) (prn "when has an implicit do")) ; Condition with assignment using `if-let` or `when-let`: (when-let [one (- answer 41)] (prn "when-let" one))
