Mnemonist is a curated collection of data structures for JavaScript and TypeScript, including classics like heaps, tries, and queues as well as exotic ones like Burkhard-Keller trees, Bloom filters, and suffix arrays. It is fully modular, performant, and typed for comfortable TypeScript use.
Use cases
- use a heap or priority queue in JavaScript
- implement an LRU cache in Node.js
- build an inverted index for search
- fuzzy string matching with SymSpell
- use a trie or BK-tree in TypeScript
- need a bloom filter or bitset in JS
When to choose
- you need data structures missing from JavaScript's standard library
- you want modular imports without pulling in a whole library
- you work in TypeScript and want typed data structures
When to avoid
- you need a graph data structure (use graphology instead)
- you need extreme performance of a low-level language
- you only need structures already available in standard JS objects
