The term '''dynamic programming language''' does not have a precise definition, but it is nevertheless useful to refer to what distinguishes "dynamic" languages such as [[Perl]] and [[Python programming language|Python]] from more traditional languages such as [[C (programming language)|C]], [[C Plus Plus|C++]], and [[Java programming language|Java]]. Not all languages considered dynamic will have all of the features below, and some non-dynamic languages will share some of them or have some way to achieve the same effect; the reader should assume that there are exceptions nearly all of the generalizations below.

Traditional programming languages require that the program be annotated with extra information (such as [[Datatype#Explicit_or_implicit_declaration_and_inference|type declarations]]) that makes the compile-time checking possible. Dynamic languages dispense with these annotations because they use extra information available at runtime instead. In particular, they are [[dynamic typing|dynamically typed]], and use [[garbage collection (computer science)|automatic memory management]].
