Ink by Example: Loops

Instead of a `for` loop construct, we use tail recursion. The standard library contains utility functions — like `std.each`, `std.map`, and `std.reduce` — that can be used in place of a `for` loop.
	std := load('../vendor/std') log := std.log reduce := std.reduce each := std.each map := std.map
	numbers := [0, 1, 2, 3, 4, 5, 6]
We can loop over a list with `std.each`, which accepts a list and a function as arguments.	logger := num => log(num) each(numbers, logger)
Let's create a new list with the squares of these numbers with `std.map`.	squares := map(numbers, num => num * num) log(squares)
We can get the sum of these squares by using `std.reduce`.	sum := reduce(squares, (acc, num) => acc + num, 0) log(sum)
