I was a huge fan of Knockout for many years. Durandal was neat at the time, too, as a very simple "SPA framework" on top of just Knockout. I find it a bit unfortunate that Knockout 3 seems to be showing its age at this point and is maybe not something I'd recommend in 2022. I think you can almost do more, easily and handier, with Vanilla ES2020+ than Knockout. Though I certainly wouldn't recommend against Knockout either today. It's one of the few toolkits of that age that is still seeing somewhat active security maintenance, at least. There's also rumors that there may still be a production-ready "Knockout 4" in the pipeline one day. I'm still somewhat curious to see Knockout further modernized. (Search for "TKO.js" to see a preview. Allegedly, some groups are using TKO in Production already today, though it is under-documented and "unfinished".)
