We’ve seen significant interest in folks wanting greater “device flexibility”, and so we’re excited to allow devs to use the tools they love from anywhere, and on any device. Since the browser is the universal app distribution platform, having a full-fidelity VS Code-based web editor, along with a powerful compute runtime, provides you with a companion tool (along with your desktop client) to choose the right tool for each task.
I assume that if you're trying to do this, you've got a keyboard attached to your iPad - I think I'd rather stick forks in my eyes than try to code with an on-screen keyboard. So at that point, why not just use a laptop?
The Apple folio keyboard is actually really good. Even compared to my 12" Macbook the 11" iPad Pro is still more portable, plus I use the Apple Pencil a lot.
