18:30 Intro by Host Neciu Dan

18:45 The Package Was Fine Yesterday: Why Your Dependencies Are a Security Risk - and What to Do About It
Speaker: Vitaly Baev, Senior Frontend Engineer @ Revolut

Every JS project relies heavily on third-party code. Some of it runs during install, some in CI, some inside the editor, and some with access to real credentials. This talk explains how recent supply-chain attacks abused that trust and what developers can do to reduce risk without stopping delivery.

19:20 Under the hood: How V8 powers your JS apps (and why you should care)
Speaker: Gwyneth Rose, Senior Engineer at Lodgify

You've transpiled your JavaScript, minified it, chunked it, and sent it to your CDN. But what happens when the code actually hits the browser? In this talk, we'll walk through the workings of V8, the JavaScript engine that powers Chromium-based browsers and Node.js. We'll focus on its JIT (just-in-time) compiler, how it learns about your code at runtime, and how it optimizes for performance as you use a web app. We'll also go over concrete techniques to make the JIT compiler's job easier, helping you stay in V8's fastest execution path.

19:50: Drinks and networking!

20:45 Meetup finished
