If you were new to React or Angular, but needing to choose one for a single developer project, which would it be now in 2019?
TLDR - Choose React.
React is also much less abstraction away from vanilla JS. Learning Angular is learning a new language with a whole bunch of restrictions. Learning React is like learning JS++.
(This is my personal experience based on three Angular projects and ten+ React projects.)
although, code separation is native in React now and if you think http clients is still a thing you're too far into the Angular ecosystem to be helped.
