What we’re about

Undefined.js is a meetup for JavaScript enthusiasts.

Undefined.js focuses on the last trends of JavaScript development being tuned to web and mobile development. For each event, we invite some of the most brilliant minds in the JavaScript community to share their knowledge with us.

Undefined.js is a free event promoted by RedLight Software meant to be shared with and by the community. We invite you to show up and don't forget to confirm your presence - seats are limited to each venue.
