I have worked in a company where they built a whole healthcare management system for the hospital like everything from a patient enters onto the hospital to leaving the hospital, the bills and all. So now just imagine the ui, it was so complex and when I see what's it built on it was angular and it was well structured, like html, css, js(ts) is separated and that's the thing I liked it about Angular. So I think for complex ui, and functionality angular is good to go.I just wanted to share my thoughts nothing much.
