In what way does the arrow syntax in switch expressions prevent fall-through bugs?

Answer
Arrow syntax directly associates cases with outcomes, eliminating fall-through.
The '->' arrow syntax in switch expressions directly links each case to its outcome, inherently preventing fall-through bugs that are common in traditional switch statements where 'break' might be accidentally omitted. This is particularly useful in scenarios like mapping user input to actions, where skipping cases can lead to incorrect behavior.
