What CodeDam is

CodeDam is a visual coding playground for learning programming through projects. In its web interface, learners arrange visual blocks and view the corresponding code in JavaScript or Python. This connects a visual way of working with two programming languages, so learners can explore how block-based work relates to written code. CodeDam also covers computer science topics and supports project-based learning. Projects can be saved and downloaded, giving learners a way to keep a copy of their work. The Free plan costs nothing and includes the visual block-coding playground, JavaScript and Python code previews, and the ability to save and download projects. CodeDam is suited to learners who want a visual starting point for programming, as well as people who want to build projects while encountering computer science concepts. It runs on the web. Visit codedam.eu to access the playground and use its free plan.
