Angular sucks, I always knew it, and now we have some data that it’s broken even for agents. I’m not surprised
If you aim to make small apps that don’t represent complex real-world applications you should not use Angular.
But blanket statements like yours are what I hate the most in software industry.
I've built large FE systems with millions of lines of code pushing tens of billions of dolllars in revenue (I was lead FE dev on that one).
The idea that failing to do a small project (that should be clearly represented in the training data) means failing even harder at bigger projects doesn't suddenly gain merit because I have a lot of experience and have worked on big projects.
Your first sentence is telling me you were in more of a bike shedding projects than skyscraper one.
Not necessarily that Angular would win that, but I imagine that it would at least significantly shuffle the order.
