Thingies: TypeScript Utility Library

Thingies is a versatile TypeScript utility library providing a collection of small, focused, and performant helpers for common programming tasks. It covers areas such as caching (LruCache, LruMap, LruTtlMap), promise management (Defer, of, promiseMap, until, tick, timeout), string manipulation (base64, hash, randomStr, normalizeEmail, dataUri), and concurrency control (Locks, codeMutex, concurrency, FanOut). The current stable version is 2.6.0, with frequent minor and patch releases introducing new features and performance improvements. Its key differentiator lies in its breadth of specific, often low-level, utilities, all designed with a TypeScript-first approach, offering strong typing and a comprehensive API for various Node.js and browser environments.
