Sencha, part of Idera, Inc., today announced JS Days 2026 — a free two-day virtual JavaScript conference taking place on September 16–17, 2026. The event brings together JavaScript developers, front-end engineers, software architects, and engineering leaders from around the world for practitioner-led sessions on the topics shaping modern JavaScript engineering.
Registration is open now at jsdays.io. Attendance is free, virtual, and open to developers globally with no travel, cost, or approval required.
"JavaScript sits at the center of modern application development, and the demands on developers have never been higher. JS Days 2026 is our way of giving the community what it actually needs — practical sessions, real case studies, and honest perspectives from people who ship code for a living." — James Cahill, General Manager, Sencha
About the Event
JS Days 2026 is a fully virtual event designed to serve developers navigating the fast-moving JavaScript landscape. The 2026 program focuses on the questions real teams are working through — modern architecture, AI-assisted development, cross-framework interoperability, UI design for enterprise applications, and delivery patterns that scale.
Sessions are 45 minutes each, with live Q&A and open discussion rooms after each track. The two-day format is structured to move fast and stay focused — enough time to cover meaningful topics without the padding that fills longer conference formats.

Modular frontend architecture and scalable UI systems
Cross-framework interoperability (Ext JS, React, and legacy stacks)
