Sure, you can have your LLM code with any JavaScript framework you want, as long as you don't mind it randomly dropping React code and React-isms in the middle of your app.
If we're not there already, it's just a matter of time before LLMs will be able to read and understand a framework they haven't seen before and be able to use it anyway.
LLMs are already trained on JavaScript at a deep level; as LLM reasoning and RAG techniques improve, there will be a time in the not-too-distant future when an LLM can be pointed to the website of a new framework and be able to use it.
There's actually a huge twist to this: JS people deprecate things so fast that most of the training data will be for a version that either warns about deprecations on every run, or has been fully removed from the API.
To be honest I am being positive and hopefully we'll see an explosion of AI agent that will help iron out all the bug in FOSS that is hosted on different source code hosting platform. Renovate on steroid. I would work on that if my daytime job wasn't my main and only source of revenue.
Ask a FOSS maintainer and they will not be nearly as optimistic about AI reducing the amount of bugs. A lot of AI generated pull requests are broken or useless and the up wasting a lot of the maintainers' time
Think how much training has been done on such Javascript frameworks... no one stops wondering what the outcome would be. The only fact that when I ask to create an app, without any further detail about what to use, and it defaults on React, imo it's a total failure whatever the agent
