TRE is an object-oriented, functional programming language. The main goal when designing it was to create a simple to use tool that will enable users to easily discover how computer programs work under the hood. It focuses on the concepts of the "heap" and the "stack", which are the basis for many existing programming languages. TRE comes with a graphical IDE, that makes it even easier to explore the world of algorithms. Drag-and-drop functionality doesn't require learning a new language all over again. It's that simple. Are you a pro use? You can type your program in, if you want. You can also get started in no time by choosing a program from many predefind and ready to use ones.
