As developers we stand on the shoulders of giants, and it can be helpful to take a look at the past to gain a better perspective. In this talk we’ll briefly explore the past decade of backend development and architectural patterns.We’ve often ditched technologies in an attempt to make the developer experience frictionless. However we sometimes forget what we can learn from “the good old days”.What are you building: a monolith, a microservices system or something in between? A shift in how we see things can help us keep moving forwards.

Solid caught the eye of the frontend community by re-popularizing reactive programming with its compelling use of Signals to render without re-renders. We've seen them adopted in the past year in everything from Preact to Angular. Signals offer a powerful set of primitives that ensure that your UI is in sync with your state independent of components. A universal language for the frontend user interface.But what about Async?

Few developers enjoy debugging, and debugging can be complex for modern web apps because of the multiple frameworks, languages, and libraries used. But, developer tools have come a long way in making the process easier. In this talk, Jecelyn will dig into the modern state of debugging, improvements in DevTools, and how you can use them to reliably debug your apps.

Ever loaded a font from the Google Fonts CDN? Or added the loading=lazy attribute onto an image? These optimizations are recommended all over the web – but, sometimes, they make your app not faster but slower.In this talk, Ivan will show when some common performance optimizations backfire – and what we need to do to avoid that.

We use frameworks to make building our applications easier. Yet as the application scales, its performance suffers. There is no one thing, but rather a death by thousand cuts. Developers are under pressure, and they often choose the easy and quick path to deliver a feature rather than the performant path.

How many ways do you know to do iteration with JavaScript and Node.js? While, for loop, for...in, for..of, .map(), .forEach(), streams, iterators, etc!
