In which framework is your Front-end developed?

I am interested in people who have tried generative AI coding projects.  In your experience, are there project attributes that make generative AI coding capabilities a "good fit"?  Are there project attributes that are likely indicators that generative AI will not result in something useful?  I would think complexity of requirements is a big factor.  If the complexity of the project or its requirements is low - I assume genAI coding can get you within the ballpark.  For instance, logic stores: if your project has critical business logic spread out all over the place and not centralized I think that generative AI would not be able to make sufficient sense of that.
