JavaScript Standard Data Structures Library

js-sdsl is a comprehensive JavaScript library providing various standard data structures, designed to offer high performance comparable to C++ STL. It includes implementations for structures like Stack, Queue, PriorityQueue, Vector, LinkedList, Deque, OrderedSet, OrderedMap, HashSet, and HashMap. The library is currently on stable version 4.4.2, actively maintained with a regular release cadence as seen by frequent updates within the 4.x series. Its key differentiators include optimized performance that often surpasses other popular JavaScript data structure libraries (e.g., Denque), a lightweight footprint (~9KB compressed), and a lack of external dependencies. It also provides C++ STL-like bidirectional iterators and ships with full TypeScript type definitions, making it suitable for modern JavaScript and TypeScript projects that require efficient, robust data management.
