The Main Thread Is Not Yours — Den Odell

Every millisecond you spend executing JavaScript is a millisecond the browser can’t spend responding to a click, updating a scroll position, or acknowledging that the user did just try to type something. When your code runs long, you’re not causing “jank” in some abstract technical sense; you’re ignoring someone who’s trying to talk to you.

This is a great way to think about client-side JavaScript!

Also:

Before your application code runs a single line, your framework has already spent some of the user’s main thread budget on initialization, hydration, and virtual DOM reconciliation.

You might not need (much) JavaScript for these common interface patterns.

While we all love the power and flexibility JS provides, we should also respect it, and our users, by limiting its use to only what it needs to do.

Yes! Client-side JavaScript should do what only client-side JavaScript can do.

This is a spot-on analysis of how CSS-in-JS failed to deliver on any of its promises:

CSS-in-JS was born out of good intentions — modularity, predictability and componentization. But what we got was complexity disguised as progress.

Escape Velocity: Break Free from Framework Gravity — Den Odell

React is no longer just a library. It’s a full ecosystem that defines how frontend developers are allowed to think.

Real talk!

Browsers now ship View Transitions, Container Queries, and smarter scheduling primitives. The platform keeps evolving at a fair pace, but most teams won’t touch these capabilities until React officially wraps them in a hook or they show up in Next.js docs.

Innovation keeps happening right across the ecosystem, but for many it only becomes “real” once React validates the approach. Which is fine, assuming you enjoy waiting for permission to use the platform you’re already building on.

Zing!

The critique isn’t that React is bad, but that treating any single framework as infrastructure creates blind spots in how we think and build. When React becomes the lens through which we see the web, we stop noticing what the platform itself can already do, and we stop reaching for native solutions because we’re waiting for the framework-approved version to show up first.

If your team’s evolution depends on a single framework’s roadmap, you are not steering your product; you are waiting for permission to move.
