Blockly is a visual programming language that allows users to create code by stacking blocks together, similar to building with LEGO. It is designed to be user-friendly, making it accessible for beginners, especially children. Users can drag and drop blocks that represent different programming concepts, such as loops and conditionals, to create functional programs without needing to write text-based code. Developed by Google, Blockly is often used in educational settings to teach programming fundamentals. It can be integrated into various applications and platforms, allowing users to see the corresponding text-based code as they build their projects. This helps bridge the gap between visual and traditional coding.
