In computer science, a dynamic programming language is a class of high-level programming languages, which at runtime execute many common programming behaviours that static programming languages perform during compilation. These behaviors could include an extension of the program, by adding new code, by extending objects and definitions, or by modifying the type system. Although similar behaviors can be emulated in nearly any language, with varying degre… WebDynamic type systems are intrinsically more flexible and more abstract. The higher degree of abstraction allows for more expressive and versatile language constructs.
