Match Control

The 'match' statement evaluates an expression and executes the code block corresponding to the first matching value. It provides a formal and readable alternative to multiple conditional checks.

let score = 90

match (score) {
    90 => println("Passed")
    75 => println("Ok")
    default => println("Not in the list")
}

The 'default' case ensures that the program has a fallback execution path if no other patterns match the provided expression.

let status = "error"

match (status) {
    "success" => println("Operation completed")
    "error" => println("System failure detected")
    default => println("Unknown status")
}
