General
Simplify function type check

Simplify the condition by removing the redundant message && check, as typeof
message === "function" is sufficient to check if message is a function.

@commitlint/cz-commitlint/src/Process.test.ts [22]

-message && typeof message === "function"
+typeof message === "function"
  • Apply / Chat
Suggestion importance[1-10]: 4

__

Why: The suggestion correctly identifies that the message && check is redundant, as typeof message === "function" already handles cases where message is falsy. Applying this change simplifies the code.
