A JavaScript library providing implementations of common data structures such as lists, sets, maps, splay trees, and LRU caches with idiomatic, observable interfaces. It works in Node.js and browsers via CommonJS loaders or a standalone script tag.

Use cases

• look up values by arbitrary keys in JavaScript
• use an LRU cache that evicts least recently used entries
• observe changes to collections reactively
• keep a collection sorted automatically
• use sets and maps that work with object keys in older JavaScript environments

When to choose

• you need specialized data structures (splay trees, LRU/LFU caches, observable collections) in Node or the browser
• you need a consistent generic method interface across different collection types
• you must support older JavaScript runtimes lacking native Map/Set

When to avoid

• you only need native Map, Set, or Array features available in modern JavaScript
• you want a library under active development with frequent updates
• you need strongly typed or immutable collections
