Now replace def to_int(a, b): ... with the JS semantic equivalent of def to_int(*args): ... because that's how JS function declarations work. You simply have the option to assign names to positional parameters, i.e. function fn(a, b) { comnsole.log(a, b) } is just syntactic sugar for function fn() { const a = arguments[0] const b = arguments[1] console.log(a, b) } and that's what people seem to struggle with and argument over for whatever strange reason.
