TaffyDB In-Memory JavaScript Database

TaffyDB is an open-source JavaScript library that provides an in-memory database solution for both browser and Node.js environments. It allows developers to store and manipulate JSON data as 'tables' using a uniform, SQL-like interface. Currently at version 2.7.3, the library emphasizes stability and reliability, having been used in production for many years. It differentiates itself by offering a JavaScript-centric data selection engine with features like insert, update, unique, and count, all while being compatible with various DOM libraries and modern browsers (IE9+, FF3+, Safari 5+, Chrome 1.0+) and Node.js 0.10+. While stable, the project's focus appears to be on expanding regression test coverage rather than rapid feature development, suggesting a maintenance-oriented release cadence.
