In case of TS vs JS it's well advertised that: > existing working JavaScript code is also TypeScript code For C++, it's been decades since anything like that was true. > C++ is, like Typescript to Javascript, almost a superset of C except for a few changes that break things. "Almost" and "few changes" are doing some heavy lifting here. Advertising and insisting incorrectly that C++ is a superset is only doing harm to both languages and causing confusion like the one in the post. It might have been true some 30+ years ago, but let's stop spreading it (outside of historical context) and misinforming others.
