Coding and debugging should flow, not fizzle! Let's see what's new and improved in Chrome DevTools to make your web development & debugging journey smooth sailing.

As developers, we spend much of our time debugging apps - often code we didn't even write. Sadly, few developers have ever been taught how to approach debugging - it's something most of us learn through painful experience.  The good news is you _can_ learn how to debug effectively, and there's several key techniques and tools you can use for debugging JS and React apps.

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.

Embark on a journey beyond console logs! This session unveils the power of observability in the world of JavaScript, offering practical insights and real-world examples to supercharge your development workflow. From pinpointing elusive bugs to optimizing user experiences, discover the art of making your code transparent, traceable, and resilient. Elevate your JavaScript craftsmanship with the mastery of observability.
JavaScript development is evolving, and so should your approach to understanding and optimizing code. This session arms you with the knowledge and tools needed to stay ahead in the ever-changing landscape of web development.

Like it or not, those days lots of things around us run on JavaScript. Web, mobile and desktop apps, TVs, fridges and space rockets - you name it! I will talk about how to put this to good use by utilizing the forbidden craft of "disassembling". We'll also talk about not knowing things, trusting facts and becoming a better engineer.

Have you ever wondered how screen readers interact with browsers to provide accessible experiences? You may have heard terms like "accessibility APIs", “accessibility tree” or "accessible name computation". But what do they refer to, really? In this talk, we will demystify the process in which browsers generate and update the accessibility tree. We will look into its key elements, and how HTML elements and ARIA attributes map into it. Lastly, we will explore how web developers can leverage it for effective debugging. Let's dive into the inner workings of screen readers-browsers interactions!

React's component model and one-way data flow give us a great mental model for building our apps, but debugging React apps can still be confusing. React's internals are a black box, and it's often hard to understand why components rendered or what caused errors.
The Replay time-travel debugger makes it easier to debug React apps by letting you inspect what's happening at any point in time. But what if we could go beyond the usual debugger features, and build new debugging features that tell us more about what React is doing? Let's see how Replay's API makes that possible.

We are all using static analysis tools like ESLint every day to ensure the better quality of our code. How does it work, and what is tricky about JavaScript, making writing a proper rule often not trivial?

POV: Your app has a crash affecting thousands of users, but for the life of you, you can't reproduce it and have no idea what's causing it. Hear the story of an epic struggle to vanquish a non reproducible bug and learn what to do (and what not to do) when facing such a foe.

Jecelyn will share some tips and tricks to help you debug your web app effectively with Chrome DevTools.
