Greedy Algorithms and Priority Queues in JavaScript Systems
In the previous article, we treated heaps as a systems primitive: a way to make “what should run next?” efficient in event-driven JavaScript systems. We focused on the mechanics of binary heaps, their complexity, and how they underpin timer queues and schedulers.
This article shifts the emphasis from the data structure to the algorithmic pattern that naturally sits on top of it: greedy algorithms.
