The implementation is not currently stable and is in active development. It's best seen\nas an experiment to explore how Algebraic Effects can improve (or degrade) application development. And an early-stages proposal for the addition of a mechanism to facilitate Algebraic Effects in ECMAScript.\n\nTLDR: _DON'T USE THIS IN PROD_.\n\nLooking for how \u0026 why of effectjs?
