JavaScript Monthly London Meetup
Javascript evolution has sped up (a lot) in recent years and event the most veterans developers find it hard to keep up with the latest trends. This meetup group aims to bring you monthly bite-sized updates on the world of Javascript along with a healthy dose of nice people, beer and pizza.
- Please use your full name when registering, as some of our venues require a full list of attendees beforehand. You have an idea and you want to be a speaker?
We are always looking for more speakers - submit your talk here (https://docs.google.com/forms/d/e/1FAIpQLSdFaatfveOUbrmer47jYb5J4J4ttxAFc1CgTjUDltBXmDOJmg/viewform)
So what will you build?
Right now you can build faster than ever. You have ‘Everything as a Service’; Hundreds of AI agents at your disposal with no workers' union. And JavaScript runs on virtually every internet connected device on the planet. Scary huh?
In this talk I’ll share practices I’ve seen work as an IC, a manager, and a manager of managers, and what remains important when zooming out from line by line implementation.

ErrorScript: Building a TypeScript Feature That Should (Probably) Be Rejected
I built ErrorScript: TypeScript with "Safe" Exceptions. Unhandled exceptions and dropped promises become part of the type system and raise compile-time errors.
It works. It feels native. And it probably shouldn’t exist.
This talk explores what ErrorScript reveals about how we model failure in code, how language design influences behaviour, and the trade-offs that make this feature unlikely to be adopted.

Pear: Hold my peer
Why can't technology companies avoid central points of failure? A casual chat about the clothes the emperor isn't wearing and an introduction to a real-world battle-tested anti-fragile approach to building and deploying applications: Pear.

Silicon Valley Is Optional. GitHub Is Not. How to commit your way into the AI boom and how OpenJS is shaping responsible AI in the open.
Silicon Valley is buzzing again. Dozens of nightly AI meetups, packed co-working spaces, and a lot of hype. But the real action isn’t in a postal code. It’s on GitHub.
This talk breaks down why JavaScript is powering the AI boom globally, and why you don’t need a Valley badge to be part of it. Just open an issue and commit.
AI-assisted development is becoming part of modern workflows. The goal isn’t to redefine open source. It’s to make sure that as tools evolve, accountability, transparency, and maintainership stay intact.

Superpositioned Infraestructure and distributed Javascript
Serverless reduced operational burden, but it never truly removed infrastructure. This talk explores superpositioned infrastructure and how Module Federation turns distributed JavaScript into a runtime-defined system, where compute and code are decoupled and services can be composed dynamically instead of being pinned to a single deployment surface.
