''A '''software framework''' is a reusable design for a software system (or subsystem). This is expressed as a set of [[:Wikipedia:abstract class|abstract class]]es and the way their instances collaborate for a specific type of software. Software frameworks can be [[:Wikipedia:Object-oriented programming|object-oriented designs]]. Although designs don't have to be implemented in an object-oriented language, they usually are. A software framework may include support programs, code [[Wikipedia:Libraries|libraries]]<ref>See also [[PHP libraries]] bundled with Joomla!</ref>, a [[Wikipedia:JavaScript|scripting language]]<ref>See also [[JavaScript libraries]] bundled with Joomla!</ref>, or other software to help develop and ''glue together'' the different components of a software project. Various parts of the framework may be exposed through an application programming interface ([[Wikipedia:Application programming interface|API]]).''
