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.

I Built the Same App 10 Times: Evaluating Frameworks for Mobile Performance | Loren Stewart

A very, very deep dive into like-for-like comparison of JavaScript frameworks. The takeaway:

Nuxt demonstrates that established “big three” frameworks can achieve next-gen performance when properly configured. Vue’s architecture allows competitive mobile web performance while maintaining a mature ecosystem. React and Angular show no path to similar results.

And the real takeaway:

Mobile is the web. These measurements matter because mobile web is the primary internet for billions of people.

Build for that reality.
