Functions¶

Definition¶

Functions support export Function names should be in snake_case.

func factorial(n: Number) -> Number {
    if n == 0 {
        return 1
    }
    return n * factorial(n - 1)
}

The expression is evaluated at the time of function calling.

func factorial(n: Number = 1) -> Number {}

# positional arguments
factorial(10)
# keyword arguments
factorial(n: 10)

exporting a main function makes a module executable

MyScript.moka

export func main() {

}

moka run MyScript.moka
