A priority queue can be implemented in TypeScript using a binary heap, where elements are inserted and removed based on their priority.

A priority queue is a specialized data structure where each element has a priority, and elements are served based on their priority rather than their insertion order. In TypeScript, you can implement a priority queue using a binary heap, a complete binary tree where each parent node is either greater than or less than its children (max-heap or min-heap). In a priority queue, the element with the highest priority is dequeued first. The two main operations are enqueue (insert) and dequeue (remove the element with the highest priority), both of which can be implemented with O(log n) time complexity in a binary heap. Priority queues are commonly used in algorithms like Dijkstra’s shortest path, Huffman coding, and scheduling processes in operating systems. Implementing a priority queue in TypeScript helps you manage data that requires ordering based on priority.
