'''Build Your Own Blocks''' or shorter '''BYOB''' (renamed '''"Snap!"''' from version 4 in 2013) is an [[educational programming language]] and multimedia [[authoring tool]] that can be - like the [[Scratch (programming language)|Scratch]] which provided inspiration for a children-friendly [[GUI]] - used by pupils, teachers, and parents for a range of educational and entertainment projects from [[math]] and [[natural science|science]] projects, including simulations and visualizations of experiments, recording lectures with animated presentations, to [[social sciences]] animated stories, and [[interactive art]] and music.

'''BYOB''' is an [[open-source]] early [[educational programming language|software development]] learning environment which has inherited [[Scratch programming language|Scratch]]'s intuitive [[LEGO#Robotics_sets|LEGO]]-like software development interface for children and students.

==Features==

The acronym stands for "Build your own blocks."

The most important features which differentiate BYOB from Scratch, include:

*[[first class function|first class]] functions or procedures (their mathematical foundations are called also "[[Lambda calculus]]"),

*[[first class object|first class]] lists (including ''lists of lists''),

*''first class'' sprites (in other words [[Prototype-based programming|prototype-oriented instance-based classless programming]]),

*nestable sprites

==Online and offline versions==

New powerful options are however being put in young children's and students' hands. Such as the option to create custom made ("build your own") blocks, [[first class function|first class]] functions or procedures (their mathematical foundations are called also "[[Lambda calculus]]"), [[first class object|first class]] lists (including ''lists of lists''), and ''first class'' sprites. In other words [[Prototype-based programming|prototype-oriented instance-based classless programming]], which is not part of the simpler [[Scratch programming language|Scratch]] it is based upon.
