C++ the good parts exclusively uses on stack allocation and passing by const reference without ever introducing pointers.
You know this to be true.
Pointers is a pathway to memory that some consider to be… unnatural
Because its essential for application use where memory management becomes extremely vital, usually due to the rom or memory to be extremely linited in size. Worrying about memory management (something C++ makes mandatory) is something not all programmers need to care about, but having automated memory mangement is also what causes bloat that comes with modern applications, due to bad programming practices of not caring about it.
The majority of dumb stuff in Javascript is that it has some counterintuitive way of doing something that it shouldn’t do at all, so only teaching the good parts works. So teaching just the good parts is pretty reasonable.
The only thing you need to know is goto statements
The problem is everyone disagrees on what part of C++ is good… Some like C+classes. Some like intense meta programming and some like functional programming and all are valid C++ that people advocate for.
It sounds like a lie to me. Everyone knows there are no good parts of JavaScript.
