    Fast forward to now and we are learning more about Jotai, a Recoil alternative from Poimandres ( creators of react-three-fiber, etc.). Needless to say, we were very excited when we stumbled upon Jotai Issue #44, a discussion concerning focusable atoms started by Meris Bahtijaragic and the compelling work that resulted, jotai-optics. This code wraps another library we have been very intrigued by as of late, optics-ts which provides a whole new level of typesafe, functional goodness.
