I have to admit I am getting lost in all these new language constructs :(. I worry that soon I will not be able to read TS code of more experienced programmers.

I have to admit I am getting lost in all these new language constructs :(. I worry that soon I will not be able to read TS code of more experienced programmers. That being said, the only way forward is to learn! But there seems to be total lack of solid learning resources with plentiful of examples and most importantly "best practices" that explain why the new construct is better and when to use it over the old way.
