Coding
Code Monster
Short JavaScript examples sit beside a drawing area, so every edit changes the picture right away.
Code Monster places small pieces of JavaScript next to what they draw. Lessons begin with shapes and colours and move toward animation and more complex patterns, introducing variables, loops, conditions and functions through examples. Reset and back controls return to an earlier version when an experiment goes sideways.

Notes for parents
According to the publisher, it is designed for a computer with a keyboard, not for mobile. Progress stays in the same browser on the same machine rather than in an account. It is an introduction to JavaScript rather than a full course.
