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.

Mima, the serverless social client built in JavaScript, running in a browser

RL Nabors spent years on the React core team at Meta and on browser teams before that. Now they're building an omni-client combining X, LinkedIn, Bluesky and Mastodon content streams and publications in one private app, with no algorithm. Mima (mima.social) launched in San Francisco last month.

RL will demo it live, then take questions about local models and the future of the web in the agentic era.

The Dependency Graph Your Tests Can't See

A model I was working with scored R squared 0.998 on public US data. One of the input columns had been calculated from the target by the same agency that published both, so the model was rediscovering a formula it had already been handed. Tests don't catch this. Nothing throws, nothing fails, the numbers look great. So I built a linter for it. You write a manifest of what derives from what, the tool walks the graph, and CI goes red when a feature sits on a derivation path to or from your target. It returns four verdicts, including one for columns whose provenance nobody has traced yet. The code is Python. The idea applies anywhere you have a dependency graph and a CI job. I'll show the leak, the manifest, the linter, and a run going red live.

From Prompts to Systems: How I’m Building with AI at 15

What happens when you stop treating AI as a chatbot and start building systems around it?

At 15, I’m using AI to build businesses, create content and manage my everyday work. In this talk, I’ll share how I’ve gone from experimenting with different AI tools to developing practical workflows across my business, Vajra Works, my personal brand and my productivity systems.

I’ll explore how I choose the right tools, structure workflows, decide what to automate and keep human judgment involved. Through real examples, demonstrations and lessons from things that haven’t worked, I’ll show how AI can move beyond prompts into systems that help get meaningful work done.

The goal is to make this a practical and valuable session for the developer audience.
