do_times(n, fn, @key from = 0, init)

Return the final value of the function fn, after calling it n times.

The starting value of n is specified by the from keyword argument. Fn take three arguments - the current value of n, the value returned by the previous call to fn and a function that can be called to exit from the loop prematurely. The initial value of the second argument is specified by the init keyword argument.


do_times(5, ^(n, p, _) n + p, init = 0)
// 10

do_times(5, ^(n, p, return) if (n == 4) return(p) else n + p, init = 0);
// 6
