Contracts would be interesting, but perhaps too expensive?
fib :: (Number) -> Number
function fib(n) {
return n == 0? 0
: n == 1? 1
: fib(n - 1) + fib(n - 2)
}
or function fib(n Number) -> Number { }
Not particularly proposing any syntax though. Not particularly keen on using
fixed types though -- as JS is not statically typed and types are not
particularly well defined, definitely not something I'd check for is-a
relationships --, I'd rather go with a predicate functions, but then that's
even more expensive.
