Snap! is a visual programming language designed to help users, especially beginners, learn coding concepts. It allows users to create interactive programs by snapping together blocks that represent different commands and functions. This block-based approach makes it easier to understand programming logic without needing to write complex code. Snap! is built on the principles of Scratch, another popular visual programming language. It supports advanced features like first-class lists and custom blocks, enabling users to create more sophisticated projects. Snap! is often used in educational settings to teach programming and computational thinking in a fun and engaging way.
