Summary
This was a quick look back at the evolution of Delphi's extensions to Object Pascal, reviewing the basic syntax and briefly looking at interfaces, variants, nested types, and Unicode. Generics and anonymous methods were explained, RTTI and attributes were demonstrated, and finally, inline variables, type inference, and custom managed records were covered to complete the enhancements in the most recent versions. We didn't touch on all areas of what makes Delphi such a great language (such as operator overloading or class helpers) but hopefully, you learned some additional aspects of the language that will solidify your understanding of powerful modern-day programming concepts and increase your productivity with advanced techniques.
With a firm grasp of the IDE, an understanding of the toolset, knowledge of Delphi's project types, and making fine use of the language, you are now ready to go on to the next chapter and start your deep dive into cross-platform...
