As a long time JS dev I don't claim expertise in other languages, but every time I go back to check out new features in C++ or Java they feel more and more like JavaScript with types than "C with classes".
Due to auto and templates large parts of the strong typing can be moved to the compiler. When writing modern C++ one can be quite fast (not as fast as JavaScript) but get some verification, by the compiler, which fastens development time (i.e. typos in identifiers are located easily, whereas in JS you need to run the tests and then have to find the root cause)
I think JavaScript is moving in that direction too. There are some formal proposals for bringing types and community seems to like the individual attempts such as TS and Flow as well.
That's good to know. Introduction of iterators, lambdas, first-class functions, smart pointers, references, auto and in such in C++11 and Java left me with the feeling of C family languages converging on some similar set of features that resemble JavaScript more and more.
