The sorted-array library provides TypeScript-based array subclasses that maintain continuous sorting on insertion or push operations, featuring optimized includes() and indexOf() methods for faster searches. It's designed for developers who need sorted collections without the overhead of Map or Set objects, offering three variants: basic value sorting, property-based sorting for objects, and custom comparison function sorting. The library is particularly useful for applications requiring frequent searches in sorted data, such as database indexing, leaderboard systems, or any scenario where the trade-off between slower insertions and faster lookups is acceptable.
