The short answer is that these things don't really exist anymore for most (business) applications when you stopped writing it in C.
So the things you mention indeed is experience you need to get rid of as you move to other software stacks and other technologies.
And end up writing the usual garbage that takes 2 GB of RAM just for a chat application... No. Acting like those concepts disappeared just because you write Javascript instead of C makes no sense. It still does memory allocation. You still need to manage it. Thinking that the virtual machine/compiler is doing "magic" is exactly what is wrong with most code today.
