Splay Tree Data Structures for TypeScript

splaytree-ts is a TypeScript library that provides efficient implementations of Splay Tree data structures, specifically `SplayTreeMap` and `SplayTreeSet`. Splay trees are self-balancing binary search trees with the distinct characteristic that recently accessed elements are more quickly accessible again, offering O(log(n)) amortized time complexity for fundamental operations like insertion, lookup, and removal. The current stable version is 1.0.2. Its key differentiation lies in the splaying heuristic, which optimizes for temporal locality of reference, making it particularly performant for workloads with skewed access patterns. The library supports custom comparison functions and key validation predicates for flexible use with various data types, enhancing its utility beyond simple primitive comparisons.
