In block-based coding, you create programs by dragging and attaching blocks on a canvas rather than by writing code. The blocks snap together just like Lego blocks stacking together.
Block-based coding is ideal for beginners as a first introduction to the world of programming.
It is hard to make mistakes when dragging and organizing blocks! Learners are able to rapidly see their creations in action without getting bogged down by the syntax complexities of modern programming languages.
Scratch, developed at MIT, is arguably the world’s most well known block-based programming language. MakeCode from Microsoft offers a block-based coding environment as well. Most robotics kits today (e.g., Lego Mindstorms) come with their own block-based languages. All these systems owe their intellectual origins to Scratch.
