Recent advancements in caching technology have led to the development of an efficient data structure called LRU (Least Recently Used) Cache. This innovative solution helps manage memory constraints by evicting the least recently accessed item when the cache exceeds its capacity. In JavaScript, implementing an LRU Cache is possible using a combination of a Map and Doubly Linked List. For simplicity, this implementation uses only a Map to store key-value pairs while maintaining insertion order.
