repeat

Repeat an iterable given times.

Similar: repeat, cycle, rotate, reverse.

function repeat(x, n)
// x: an iterable
// n: times [-1 ⇒ Inf]

const xiterable = require('extra-iterable');

var x = [1, 2];
[...xiterable.repeat(x, 2)];
// → [1, 2, 1, 2]

[...xiterable.repeat(x, 3)];
// → [1, 2, 1, 2, 1, 2]
