By mapping the features and capabilities of one language to an interface implemented in another language, a language binding allows a library or service written in one language to be used when developing in another language. A single API can have multiple implementations in the form of different libraries that share the same programming interface. By 1990, the API was defined simply as «a set of services available to a programmer for performing certain tasks» by technologist Carl Malamud.
