On Creating Your Own Data Structures

Note: you can create your data structures without using arrays as well, or even use my linked-list.

// using plain ole prototype not syntactic class
const Queue = function() {
  this.first = null;
  this.size = 0;
};

const QueueNode = function(data) {
  this.data = data;
  this.next = null;
};

Queue.prototype.enqueue = function(data) {
  const enqueuedNode = QueueNode(data)
  // ..
};

Queue.prototype.dequeue = function() {
  // ..
};
