Nice to see it still around and updated. The sad part is I guess this means React will be around in 2060.

Backwards compatibility. Apparently there are still some people stuck on IE11. It's nice that jQuery still supports those users and the products that they are still running.

Even after migrating to ES modules, jQuery is still somewhat bloated. It is 27 kB (minified + gzipped) [0]. In comparison, Preact is only 4.7 kB [1].

Are those people/products upgrading jQuery though?

Long-time user here. It served me well for years, though I haven't really touched it since the 3.0 days. Glad to see it's still being maintained.

jQuery does a lot more though, and includes support older browsers.

Some corporate machines still run XP. Why upgrade what works?
