do you have a good template (pun intended) on how to best learn modern c++? coming from Go and Typescript which have very mature devX tooling, c++ is a landmine to navigate. and that's when I already have professional experience with it (the place just didn't have strong c++ culture)
Try watching the "back to basics" videos from the last 4 years' cppcons.
But that's mostly learning modern paradigms of the language.
If you also mean the tooling, then it depends: Learn CMake which is sort of an industry standard. There are books and videos, but for a concrete experience, try looking through the CMakeLists.txt of some non-trivial C++ open source project.
