• enqueue(item): Adds an item to the end of the queue.
• dequeue(): Removes and returns the item from the front of the queue. Returns a message if the queue is empty.
• peek(): Returns the item at the front of the queue without removing it. Returns a message if the queue is empty.
• isEmpty(): Checks if the queue is empty. Returns true if empty, otherwise false.
• size(): Returns the number of items in the queue.
• printQueue(): Prints all items in the queue as a comma-separated string.

npm install -g namastey-queue
