“Memory management can be an overwhelming topic to navigate. This talk is the result of my journey down the rabbit hole to better understand it myself. By drawing on my research and experience, I’ve put together a comprehensive guide that covers everything from hardware implementation to the inner workings of V8.”
⏰ 13:50 — Break (10 min)

“I’ll share my experience utilizing Firebase facilities such as authentication, Realtime DB vs Firestore, Cloud Functions, Firebase ML, and others. Examples would be based on an Angular-based web app, but the practices can easily be used with React, VueJS, or any other modern FE framework.”

“These days, web performance is one of the most important things everyone wants to optimize on their apps, and it’s clear to everyone how dramatic the impact of a poorly optimized website is on business. Yet we as an industry completely fail in recognizing its complexity and widely misuse the most common tool to measure it — Google Lighthouse. If you’re one of those people thinking that good performance equals a good Lighthouse score, you’ve also fallen into this trap and this talk is for you. You will learn when the Google Lighthouse audit results can trick you and how to make good decisions based on its output.”

Build better apps using CRDTs, Eric Meier, [eng][Intermediate]

In this presentation, I will introduce CRDTs and explain how you can leverage them to achieve this.

Leveraging the Event Loop for Blazing-Fast Applications!, Michael Di Prisco, [eng][Intermediate]
“Can the Microtask Queue help you improve your performances by 100x? It turns out it can, but how? JavaScript is single-threaded, yet it provides a really powerful Event Loop to allow non-blocking operations, so let’s try to tame this beast together and get the most out of it! As I like to say: The Event Loop is the only infinite loop you’ll love.”

A Tale of Two Webs, Kyle Simpson, [eng][Beginner]
“It was the best of times, it was the worst of times…” Dickens’ famous words in “A Tale of Two Cities” lays out a timeless comparison, the paradox of how the situations we find ourselves in can be both terrible and hopeful at the same time. We’ll look at the web (past, present, and future) through these lenses, and hope to inspire the challenges and changes we should be tackling to remake the web into something better.”

Running Node.js in your browser with WebContainers, Oleksandr Zinevych, [ukr] [Intermediate]

In this talk, I’ll talk about WebContainers as another step in this direction, which brings Node.js runtime directly to your browser. Why do we need Node.js in the browser at all? Will it work in any real use case, not just on the demo site? But is it a good step in general? All this and a few more questions I will try to answer in my presentation.”
