function createNode(data, next) {
  return {
    data: data,
    next
  };
}

class LinkedList {
  _head = null;

  unshift(data) {

Tests:

Linked List
const list = new LinkedList(); let x = 10000; while(x--) { list.unshift(x); }
Array
const array = []; let x = 10000; while(x--) { array.push(x); }
Set
const s = new Set(); let x = 10000; while(x--) { s.add(x); }
