All true. I was surprised to read here that React was considered to have a shorter learning curve that Angular. Also that it’s faster.
But on their respective speeds, I’ve yet to see a real life test: eg — the same app using some APIs, some data binding, etc (one app that uses as many framework features of both as possible).
I’ve tried doing it on my own (my current company uses React because some developers have PTSD from Angular 1 & 2 — understandably) and I had plenty of examples to use for an Angular counterpart. I found rendering performance difference to be negligible (but favouring React still — more efficient DOM, Virtual vs Shadow) but developing in Angular 4 & 6 is way much faster (and easier to swallow, discarding all the boiler plate).
