HolyJS, a large Russian conference for JavaScript developers, will take place on November 8-9, 2019 in Moscow. It should not be confused with numerous frontend conferences: the talks will be not only about the frontend, but also the backend, the desktop, and work with hardware.

JavaScript is the most popular programming language in the world (according to GitHub and RedMonk), but there was no Russian JS conference before. We have changed it: HolyJS brings under one roof more than 1000 JS developers ready to discuss technical problems with JavaScript experts from all around the world.
