Frontend development - perhaps more than any other kind of software development - is “what you see is what you get”. There aren’t a lot of ways a website can be invisibly broken.
Systems engineering isn’t like that. Vibe coders beware: A database could silently corrupt data, or have latent security vulnerabilities. It might have a badly designed query language that will be difficult to change later. But frontend code can be rewritten at will. It’s a perfect target for LLMs.
> There aren’t a lot of ways a website can be invisibly broken
Any website that has any UI state management or does any kind of network calls can be invisibly broken in many, many ways
The UX is what makes the users use the apps, systems, games, their phones.
"There aren’t a lot of ways a website can be invisibly broken."
??? Have you never debugged weird react state before??? Have you never used a nontrivial SPA before? Even the most simple react SPA has about a trillion states.
I don't really know how to respond to your statement than "no, they can definitely be invisibly broken."
At the same time I have found LLMs far less competent at frontend because they don't seem to have any visual understanding of what a good website looks like.
