Gradual typing provides the benefits of both static and dynamic checking in a single language by allowing the programmer to control whether a portion of the program is type checked at compile-time or run-time by adding or removing type annotations on variables.

Gradual typing is a type system that lies inbetween static typing and in dynamic typing. Some variables and expressions may be given types.
Abstract. Gradual typing enables a mixture of static and dynamic typ- ing within the same program. There are four properties that are desirable.
Abstract. A wide range of gradual type systems have been proposed, providing many languages with the ability to mix typed and untyped code.

Abstract. Static and dynamic type systems have well-known strengths and weaknesses, and each is better suited for different programming.
