Wojciech Pilzak runs a dev community. Finding speakers + events was chaos, so he built https://t.co/ttHIwwTBtk in 200 hours: event discovery, speaker Q&A, live polls, QR tools & organizer workflows.

Now: 60 events, 100+ monthly users, growing organically. Free & open source.

Right now you can build faster than ever:Everything-as-a-Service, hundreds of AI agents W/ no workers’ union, & JavaScript running on nearly every connected device on Earth

Luke Sargeant Eng Lead https://t.co/p2YLH5ptEH shares what still matters when you zoom out from the code

[JS Monthly London & Online @jsmonthlylondon]

James builts ErrorScript: TypeScript with “safe” exceptions. Unhandled exceptions and dropped promises become compile-time errors.

It works. It feels native. And it probably shouldn’t exist.

A talk on failure & language design.

Past week was packed! @jsmonthlylondon meetup, @cityjsconf London workshop, and a stage talk about how Module Federation ideas extend into AI orchestration, from module boundaries to federated AI specialists.

A lot of this connects to what we're building at @ZephyrCloudIO.

Thanks to everyone who joined and for all the conversations afterwards!

Modern JavaScript apps push browsers to their limits, with rendering, scripting, and input competing on the main thread—causing jank & slow interactions. Ananya shows how to move work off the main thread to create faster, smoother, more responsive web experiences.
