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 PriorityQueue(4); q.enqueue("Hello", 3); q.enqueue("World", 2); q.enqueue("Foo", 8); q.display(); q.clear(); q.display();
Output
This will give the output −
[ { data: 'World', priority: 2 }, { data: 'Hello', priority: 3 }, { data: 'Foo', priority: 8 } ] [ ]
