Scratch is a block-based visual programming language developed by MIT to teach programming concepts to children. It allows users to create interactive stories, games, and animations. Programming constructs in Scratch include sequencing, loops, conditionals, variables, and threads. Scratch programs can be published online and shared with others. Scratch is commonly used by students, teachers, artists and for robotics projects through integration with devices like Lego WeDo.

15. Under The Hood SCRATCH is developed using Squeak. Squeak is a version of SmallTalkProgramming language meant specifically for multimedia application Squeak is also a Virtual Machine for Smalltalk SmallTalk has been a poster boy for Object Oriented Programming.

16. Opening the Hood Adding custom blocks to the library Such modifications are called “Mods” A few hundred Mods are available. SCRATCH 2.0 will render all current Mods useless as they intend to rewrite the whole SCRATCH.
