Snap!
Build Your Own Blocks
Overview
Snap! is a free, block-based programming language with a browser-based editor that is visually similar to Scratch but includes more advanced features. It is designed for a more rigorous introduction to computer science for high school or early college students. Key features not found in Scratch include the ability to create your own custom blocks (procedures and functions), first-class lists, first-class procedures (lambda), and nested sprites. This makes it powerful enough to teach deep computer science concepts.
✨ Key Features
- Visual, drag-and-drop programming
- Create your own custom blocks (procedures/functions)
- First-class procedures (lambda functions)
- First-class lists and sprites
- Can be used to teach advanced CS concepts like recursion and data structures
- Runs in any modern web browser
🎯 Key Differentiators
- Targets a more advanced audience (high school/college) than Scratch
- Ability to create custom blocks is a powerful tool for teaching abstraction
- First-class data types allow for teaching of more advanced computer science concepts
- Developed at UC Berkeley
Unique Value: Snap! extends the accessibility of block-based programming to cover serious computer science concepts, providing a 'high ceiling' environment for deep learning without the 'low floor' limitations of other block languages.
🎯 Use Cases (4)
✅ Best For
- The core language for the 'Beauty and Joy of Computing' (BJC) curriculum, a popular AP CSP course.
