    You need to be able to parse the code before you can compile or execute it. It helps you by creating the parser for you.
      So the parsed code goes through a compiler? And then it is executed?

        A compiler (or interpreter) has a few parts.

        A parser converts a file full of source code into a data structure.

        An interpreter traverses that data structure and executes the appropriate commands for each significant node in the structure.

        A compiler transforms that data structure and emits something else. Perhaps this other is object code for a specific processor or perhaps it's binary code for a virtual machine or perhaps it's source code for another language entirely.

        If you look at compiling and implementing languages this way, you already know the general technique. (everything is a compiler).
