Dynamic programming language is a class of high-level programming languages that execute at runtime many common behaviors that other languages might perform during compilation, if at all. These behaviors could include extension of the program, by adding new code, by extending objects and definitions, or by modifying the type system, all during program execution. These behaviors can be emulated in nearly any language of sufficient complexity, but dynamic languages provide direct tools to make use of them high-level, dynamically typed open source languages. These languages, designed to solve the problems that programmers of all abilities face in building and integrating heterogeneous systems, have proven themselves both despite and thanks to their independence from corporate platform strategies, relying instead on grassroots development and support. Ideally suited to building loosely coupled systems that adapt to changing requirements, they form the foundation of myriad programming projects, from the birth of the web to tomorrowâ„¢s challenges
