What is Scratch

Scratch is a free visual programming language developed by the MIT (Massachusetts Institute of Technology) Media Lab. Scratch is used by students, scholars, teachers, and parents to easily create animations, games, etc. It provides a stepping stone to the more advanced world of computer programming. It can also be used for a range of educational and entertainment constructionist purposes from math and science projects, including simulations and visualizations of experiments, recording lectures with animated presentations, to social sciences animated stories, and interactive art and music.Viewing the existing projects available on the Scratch website, or modifying and testing any modification without saving requires no online registration.
Scratch allows users to use event-driven programming with multiple active objects called sprites.^[Sprites can be drawn, as vector or bitmap graphics, from scratch in a simple editor that is part of Scratch, or can be imported from external sources, including webcams.
As of 2013, Scratch 2 is available online and as an application for Windows, macOS, and Linux (Adobe Air Required). The source code of Scratch 1.x is released under GPLv2 license and Scratch Source Code License.
Scratch also has its own wiki, available at https://wiki.scratch.mit.edu for members of the online community to use when unclear about features of Scratch. It covers blocks, parts of the program, features of the website, etiquette in the community, and more.
