Also known as Object Pascal, Delphi is both a programming language and an IDE for rapid application development. In fact, Delphi was designed as the successor of Turbo Pascal, a language already noted for its fast compiling times. Delphi, however, added full object-oriented programming to that foundation to become a fantastic alternative for desktop, mobile, web, and console software development.
Object Pascal is an extension to the programming language Pascal that provides object-oriented programming (OOP) features such as classes and methods. The language was originally developed by Apple Computer as Clascal for the Lisa Workshop development system.
