Using ES5 array methods with ES6 generators

Question

What\'s the correct way of using the new ES5 array functions with ES6 generators? Do I have to explicitly convert the iterable into an array first, or is there a better way?

Answer 1

Build the array using Array.from:

console.log(Array.from(range(0, 10)).reduce((x,y) => x + y));

Array.from creates an array from an iterable. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from.

If you want to do the reduce without creating the array, then you'll end up needing to do something like:

var sum = 0;
for (e of range(0, 10)) sum += e;
