linked-list definition of "head" and "tail"

the notion of “head” and “tail” seem to be backwards in the example.js. I’d expect “back” to correspond to “tail” and “front” to correspond to “head”, like this article.

the example works and tests, but it seems conceptually misleading, imo.

README:

• push (insert value at back);

example.js:

  push(value) {
    if (this.head) {
      const newHead = new Element(value);
      newHead.next = this.head;
      this.head.prev = newHead;
      this.head = newHead;
    } else {
      this.head = new Element(value);
      this.tail = this.head;
    }
  }

Changes in PR look good. But the README description is confusing (maybe because it is a doubly linked list) - I would generally expect to instead and remove from head only (aka stack). But anyways the problem specification also says the same - so seems good.

ok. PR from a fork?
