Break object into chunks of given size.

Similar: [partition], [chunk].


function chunk(x, n, s)
// x: an object
// n: chunk size [1]
// s: chunk step [n]
const object = require('extra-object');

var x = {a: 1, b: 2, c: 3, d: 4, e: 5, f: 6, g: 7, h: 8};
object.chunk(x, 3);
// → [ { a: 1, b: 2, c: 3 }, { d: 4, e: 5, f: 6 }, { g: 7, h: 8 } ]

object.chunk(x, 2, 3);
// → [ { a: 1, b: 2 }, { d: 4, e: 5 }, { g: 7, h: 8 } ]

object.chunk(x, 4, 3);
// → [
// →   { a: 1, b: 2, c: 3, d: 4 },
// →   { d: 4, e: 5, f: 6, g: 7 },
// →   { g: 7, h: 8 }
// → ]
