Hello!

Percona Server for MySQL now offers experimental support for stored programs  
in the JS language, a free and open-source alternative to Oracle’s Enterprise/  
Cloud-only feature, enabling users to write stored programs in a more modern,  
convenient, and often more familiar language.

It is still in active development, and we would very much like your feedback about it!

Binary packages based on version 8.4.5-5 are available in [Percona’s  
experimental repositories](https://docs.percona.com/percona-software-repositories/index.html), and source code is on [GitHub](https://github.com/percona/percona-server/tree/js-lang).

This topic is intended to be the place where you can ask questions, report problems  
and make suggestions about this new feature.
