JSNation 2026

about this room

The main JavaScript conference of the year brings 1,500 developers to Kromhouthal, a former ship-engine factory on Amsterdam's IJ waterfront, for a hybrid in-person day on 11 June followed by an online day on 15 June. JSNation covers the full modern JS stack — frameworks, performance, tooling, AI in the browser and the future of the language — with talks from the engineers actually shaping it. For anyone building web products in JavaScript or TypeScript, this is the room (and the after-parties) to be in.
