It’s a simple implementation of a PriorityQueue for NodeJS. As the code is JavaScript it could be used on the browser without any trouble.

The basic usage is to push() elements and give them a priority to be used into the queue. You can also set a custom compare() function and a limit of elements to be held into the queue. Any elements at the same priority will be first in, first out.

More examples can be found into the tests folder.

queue = new PriorityQueue();

queue.push(“Most important note”, 99);

queue.push(“Important note”, 50);

queue.push(“Silly notice”, 1);

x = queue.top(); // Most important note

x = queue.top(); // Important note

x = queue.top(); // Silly notice

x = queue.top(); // undefined
