+1 for @triptych
Anuglar is the joke and worst software I ever seen. It is an overengineered hell which, really, don't give you anything.
Learn software engineering and architecture, vanilla JS and ES6 itself, not frameworks. Modern JavaScript is very powerful language with all the latest changes and newest web APIs.
You can start learning React since it is simple and suck less, but I would recommend to start from the lowest level and add complexity only when you will face a real problem.
You don't need React to build powerful modern apps, you can do that with VanillaJS. People are lying you into face when telling you that React is solving a huge problem with VirtualDOM, React has invented component based architecture and separating data from UI. It has no connection to React at all.
I would recommend reading articles in this section on Medium - JavaScript scene, watching videos on this YouTube channel - FunFunFunction and reading all about ES6 and new Web APIs on MDN and Google.
