Answer
It eliminates unnecessary break statements.
Switch expressions enforce cleaner code by removing the need for break statements, which are required in traditional switch statements to prevent fall-through. This leads to fewer lines of code and reduces the risk of errors. For example, handling product categories can be done succinctly: 'switch (category) { case "Book" -> "5% discount"; default -> "No discount"; }'.
