After many headaches trying to get Numba to work with Python, I decided to just go out and learn C++. This was my main resource and can highly recommend.
As a Java dev who learned C++ at university the hate towards C++ is misplaced. C++ is a no thrills language which lets you have freedom but freedom to also shoot yourself in the foot 100+n ways, but this gives you a good foundation as a developer IMHO. Every time I think about garbage collection in Java, I can appreciate that I am not having to write code to destruct an object or worry about passing references incorr…

There are many places where C/C++ (and many other non-Rust languages) are still used, and where it would not be feasible at this time to fully rewrite them in rust.
Modern resources like the OP posted should be encouraged, as they actively teach about proper use of the language, and foot-guns to avoid (e.g. don't use c-style strings + strcpy, use smart pointers, etc).

in essence, with Modern C++, it is relatively easy to just not produce garbage which needs to be collected :-)

Why do you think C++ is like smoking?

I haven't used Java since school so I'm curious about modern Java. Do you need to worry about circular references preventing garbage collection or are there easy tools to detect such cases?

As a newbie into programming, I get pulled all the time by people to learn my first compiled language either in C++ or Rust. Every time I ask even the most innocent question in any forum it becomes a shitshow, and I can see, I'm late to the party here in HN.

That's not quite right. Consider the following program:
#include
struct A {
A (const A& other) : x{other.x} { std::cout See it on GodBolt : https://godbolt.org/z/eT8soWMxE
I don't know if this characterizes other parts of LearnCPP, haven't gone through it myself.
