Understanding WeakMap And WeakSet For Efficient Memory Management
WeakMap & WeakSet: Memory-efficient replacements for Map & Set, allowing garbage collection of keys/values without preventing cleanup, ideal for object metadata & event listener management.
In the ever-evolving landscape of JavaScript, developers are often in pursuit of more sophisticated and memory-efficient ways to manage collections of objects. Enter WeakMap and WeakSet: two types of collections that serve as memory-efficient replacements for their standard counterparts, Map and Set. Not only do they provide all the functionality of these traditional collections, but they also have the added benefit of not preventing garbage collection of their elements. In this article, we’ll dive deeply into what WeakMap and WeakSet are, examine their intricacies, and explore how and when to...
