1. A high-level declarative programming language and programming environment that treates computations as objects that send messages to one another. SmallTalk encourages the programmer to define objects in terms relevant to the intended application. The language is highly extensible because it enables you to create objects, which can be reused, quite easily. SmallTalk inspired HyperTalk, the software command language of HyperTalk, an application provided with every Macintosh produced since 1987. In this new guise, SmallTalk fulfills its goal of making programming more accessible; tens of thousand of Macintosh users have learned how to program in HyperTalk.
