About the Book

In contrast to text-based programming, block-based programming involves separating executable actions into modular units called blocks. 

Blocks are generally represented by icons, which can be selected and dragged to reorder. Users can input further information in editable fields, such as drop-down menus. The graphical representation of the code can make it easier for new users to understand the process.
