Clearing the elements of the Queue in Javascript

We can clear the contents just by reassigning the container element to an empty array. For example, 

clear() {
   this.container = [];
}

Example

You can check if this function is working fine using:

let q = new Queue(2);
q.enqueue(3);
q.enqueue(4);
q.display();
q.clear();
q.display();

Output

This will give the output:

[ 3, 4 ]
[ ]
