This one-page format using "concept" -> "example" -> "reasoning" is fantastic for people like me who used C++ a lot in the past, and haven't touched it* in decades but still want to keep up to date. It probably helps that the author understands this enough to ELI5. So Thanks Oleksandrikvl whoever you are. * And by "touched it" I mean used its deeper features, not just STL containers and simple classes (and for/auto). (I still use it for TFLiteMicro, but generally I see that most users are topical C++ programmers, like me.)
