React is a JavaScript library for building user interfaces.
React is an open-source JavaScript library for creating user interfaces that aims to address challenges encountered in developing single-page applications. React is intended to help developers build large applications that use data that changes over time. Its goal is to be simple, declarative and composable. React only handles the user interface in an app; it is considered to only be the view in the model–view–controller (MVC) software pattern.
The italian PHP user group GrUSP (Gruppo Utenti e Sviluppatori PHP - www.grusp.org) was born in the last months of 2003 and was officially launched during the second edition of the phpDay conference in October of 2004. Since then it has always tried to fullfil its goal, spreading the knowledge of PHP, its features and benefits to the italian IT community and contributing to its shift from being only an amateur scripting language to an enterprise-ready programming language.
GrUSP has grown over the years up to the current 300 subscribers, and it is now one of the biggest european PHP user groups. Its activities also include helping the creation of smaller local PUGs, translations, writing books and supporting initiatives and events of other italian web development communities.
GruSP is organizing the yearly international events phpDay and jsDay, that attract many people and companies coming from Italy, Europe and, recently, even from the United States and Canada.
