Implementing A* Pathfinding Algorithms in TypeScript for Browser Grids

Pathfinding is the backbone of any strategy or simulation game. Writing an A* pathfinding algorithm in TypeScript requires careful data structure selection for the open and closed sets—specifically using a binary heap or priority queue rather than naive array sorting to avoid massive CPU spikes during unit routing.

Sharing code snippets or discussing heuristic functions (Manhattan vs Euclidean distance) for grid-based navigation is always a great topic for game devs.
