Because applications on the web are increasingly that -- full applications.

I create scientific models and simulations for use in schools. Whether it's simulating a hurricane, or continental drift, electronics, or molecular interactions, the simulations themselves need to run on the browser, and all the UI that provides the users with all the affordances to interact with the model needs to also be written in JS/TS.

I think your questions are just revealing a failure of imagination/experience for what kinds of applications run on the web these days.

Hmm - I think that's my point - it's no longer the web is it - just a way to deliver traditional applications.

I can see if you want to write an Excel in the web - that you might have a complex code base - but surely that's the exception - not the rule?

So back to the statement of 'modern web = ts'

Isn't that wrong - these applications aren't really web - and are the exception, not the norm?

This statement is meaningless to me. What makes it "no longer the web?"

"The web" now includes fully-fledged applications. It's fine to make a distinction between things that are full applications and things that are close to blogs, if you like, but it doesn't change the fact that many people develop full applications for the web.

And I think this is clearly a lot more common you are recognizing.
