> No one can think that js has progressed substantially in the last three years

Are we talking about the language, or the wider ecosystem?

If the latter, I think a lot of people would disagree. Bun is about three years old.

Other significant changes are Node.js being able to run TypeScript files without any optional flags, or being able to use require on ES Modules. I see positive changes in the ecosystem in recent years.

That is motion not action.

The point of javascript is to display websites in the browser.

Ask yourself, in the last three years has there been a substantial improvement in the way you access websites? Or have they gotten even slower, buggier and more annoying to deal with?
