Revit MEP is a popular, high-level programming language that is object-oriented, class-based, and designed to have as few implementation dependencies as possible. It was developed by James Gosling and Sun Microsystems (later acquired by Oracle Corporation) in the mid-1990s and is now one of the most widely-used programming languages in the world. Revit MEP is used to develop various applications, including desktop, mobile, web, and enterprise applications.
