Create a simple queue using javascript

Problem description :

Create a simple queue data structure in javascript.

  • Queue organizes data into the sequential order. It similar to the a queue of people waiting to get a bus ticket. It's a first come first serve model.

  • Queue data structure supports two basic operations : enqueue and dequeue as shown below.


Logic :

  • It is similar to linked list. Linked list has a head attribute whereas Queue maintains first and last attributes.
  • I would encourage reading Create singly linked list in javascript post before reading this solution.

Solution :
