In computer science, a type system may be defined as "a tractable syntactic framework for classifying phrases according to the kinds of values they compute". A type system associates types with each computed value. By examining the flow of these values, a type system attempts to prove that no type errors can occur. The type system in question determines what constitutes a type error, but a type system generally seeks to guarantee that operations expecting a certain kind of value are not used with values for which that operation does not make sense.
