  • 3.1.1

BYOB (Build Your Own Blocks) is an open-source visual programming language developed by the University of California, Berkeley, designed to extend the capabilities of Scratch by allowing users to create custom blocks and implement higher-order functions. Released in version 3.1.1, this educational software falls under the Programming / Computer Science category and is specifically tailored for teaching computational thinking, algorithm design, and abstraction to students aged twelve and above. Unlike conventional block-based environments, BYOB enables learners to define new commands, reporters, and predicates as reusable procedures, thereby introducing concepts such as recursion, lambda expressions, and list manipulation through a drag-and-drop interface. Typical classroom use cases include introductory computer-science courses where instructors illustrate the transition from block coding to text-based languages, after-school robotics clubs that prototype sensor-control logic before exporting it to embedded hardware, and university modules that demonstrate functional programming paradigms without syntactic overhead. The single-version lineage (3.1.1) reflects a stable codebase that has remained consistent since its last major update, ensuring curricular materials and community-generated projects remain compatible over time. Because the program is distributed under a permissive license, educators often bundle it with custom libraries for data visualization, music synthesis, or Arduino integration, making it a lightweight yet expandable environment for algorithmic experimentation. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
