The biggest JS party worldwide
Who says that JavaScript is only for serious business? You can actually power an entire party by JS, and JSNation will show you how.
Amsterdam is known for its nightlife and all our attendees get an invitation to join in. If you get full access, you'll get to see various kinds of performances made with JS at the biggest JS party worldwide on June 13.
Aside from that, the extended program for in-person attendees will also offer a karaoke party and silent disco with music for everyone playing on 3 channels. Afterwards, on June 14, we'll explore the capital of the Netherlands together at walking tours and boat tours.
- So come hang out with your fellow devs in Amsterdam! June 13 – afterparty at the same venue; June 14 – walking tours and boat tours.
JS Open Source Awards
The main goal of this project is to shed some light on great open source projects that don’t receive enough attention on a regular basis.
We’re looking at OSS projects or initiatives following an open and transparent culture, especially those eager to collaborate and receive contributions from anyone interested.
GitHub stars are not our criteria, and we’re looking for hidden gems that may not have enough marketing power or huge companies behind them.
Giving back to community
We try our best to make all our events accessible and inclusive for a diverse audience. GitNation is providing 100 scholarships for underrepresented groups in tech.
