I agree with GP. When I started my career in 2000, people used C or C++ for pretty much everything. People wrote desktop GUI apps with MFC. People built web apps with cgi-bin, ISAPI, and C++ implemented COM objects consumed from asp classic. The only way to build mobile and embedded was C or C++ (PalmOS, Windows CE, later Symbian).

Eventually, some of that stuff was rewritten in languages like Java, C#, PHP, JavaScript, TypeScript. Other stuff was re-implemented for new platforms using Objective-C, or Google’s version of Java, or C# in Windows Phone/Unity/Xamarin.
