Free and open-source visual programming language and web-based IDE for coding education and simple program creation, similar to Scratch.
Blockly is a free and open-source visual programming language and web-based integrated development environment (IDE). It allows users to create programs by plugging interlocking blocks together, similar to Scratch. This makes it easier for beginners, kids, and anyone new to coding to learn programming concepts.
Blockly features a drag-and-drop interface that lets users snap together blocks of code to build programs. The blocks are categorized by color and function, like logic blocks, loop blocks, math blocks etc. Users don't need to worry about syntax and instead can focus on problem-solving and critical thinking skills.
As users create their programs by connecting blocks, Blockly generates and displays code in languages like JavaScript, Python, PHP and Dart. This shows learners what their visual blocks translate to in textual code. Blockly programs can create rich applications like games, animations and calculations.
Due to its visual and easy-to-grasp nature, Blockly is mainly geared towards educational contexts for teaching coding basics. It can introduce programming concepts like variables, functions, conditionals and more without the complexity of traditional text-based languages. Blockly is used in coding classes/camps for kids and students.
Beyond education, Blockly's web-based IDE allows for creating simple programs for tasks like math calculations, string manipulation, plotting graphs and generating dynamic content for websites. It supports extensions and APIs for expanding capabilities.
