Flattens nested iterable to given depth. 🏃 📼 📦 🌔
iterable.flat(x, [dep]);
// x: a nested iterable
// dep: maximum depth (-1)
const iterable = require('extra-iterable');
var x = [[1, 2], [3, [4, [5]]]];
[...iterable.flat(x)];
// [ 1, 2, 3, 4, 5 ]
[...iterable.flat(x, 1)];
// [ 1, 2, 3, [ 4, [ 5 ] ] ]
[...iterable.flat(x, 2)];
// [ 1, 2, 3, 4, [ 5 ] ]
