The switch statement provides an alternative way to execute different code blocks based on the value of an expression. It evaluates an expression and attempts to match it to multiple case values, requiring an exact match. Each case is terminated with a break statement unless fall-through is desired. A default case can also be included to handle any values not matched explicitly.
