JavaScript is really difficult to learn because there is so much to learn. All of that is not required to build a web app. As an integrator who puts together a web app using various libraries and frameworks, I don't see a need to learn all the nuances. Yes, I flunk interviews. But I have developed and am maintaining a robust source code that other developers can understand, if needed. So, learn JavaScript the way you want to. There is no recommended path that I can think of.
