JSNation US 2024

In a world of components written in JavaScript, CSS became a second-class citizen. But forget the memes. In this talk Tony shows how modern CSS can be a JavaScript developers best friend, saving coding time, and avoiding the kinds of styling problems that use to plague JS devs and have resulted in a myriad of competing CSS abstractions, which may not be so necessary any more.

If you had the same goals as React Compiler, what kind of React component would you write? In this talk Tony and the audience imagine they are React Compiler, rewriting a React component in the exact same way the compiler does. Along the way, we'll gain a deeper insight into React internals, to fully grasp how the compiler works, why it works that way, and how to decide if you should use it.

In this talk, Tony shows how an authoring and semantic HTML-first approach to JSX template work leads to more readable, maintainable, and accessible UI components. He demonstrates how to think through implementing a UI prototype in a semantic way, authoring HTML before visuals. He shows how accessible markup improves performance, reduces DOM size, minimizes time spent on CSS, and reduces cognitive load not only for developers, but also for all our users, no matter how they consume our sites and applications.
