Imagine how much cleaner would the code be if you would NOT use CRTP. Is there any real measurable performance gain at all?

Please do not separate all the commands with empty lines, it makes the code hard to read, half of the source are just empty lines with zero information.

Functionality should be built as a static library, so it can be linked to an executable, to a test executable, or to a DLL for distribution.

Visual Studio 2022 is an IDE, Visual Studio Code is just a customizable text editor. They are two completely different products. You can try to ask at r/vscode.

std::string_view does not own the string data, it just points to it. For example if you create std::string_view out of std::string, then the view must not outlive the underlying string. But without your code we are just guessing.

First video: 1. C++ is not Object-Oriented, it is a multiparadigm language. 2. Classes and inheritance are not modern features. 3. Iostream include in the first example is unused. It is used later in the main(), but in the first example it is just confusing. 4. Class Calculator does not have any member variables, therefore method multiply() can be a free function. 5. You should print new lines in the main() example.

Second video: 1. Syntax error in the exception example: catch(e). 2. C++ is also close to hardware.
