Description
Oh no! The King has lost his string! Ruben and Scarlet, kid Ruby masters, find it and teach all about strings along the way. But after rectifying the situation, they return to the King’s study, only to find it waist deep in water! Someone has been changing the code for the Mysterious Pipe, setting its Boolean incorrectly. This gives a nice opportunity to be educated on the properties of Booleans. Next the King, Scarlet, and Ruben must fix a train and several cooking machines, find a Dagron, and more. As they journey about the kingdom, fixing and learning code, they begin to find evidence that someone has been ruining code on purpose! Can Scarlet, Ruben, and the King catch the culprits before they escape?
This is a simple, easy-to-understand introduction to Ruby, one of the easiest programming languages. The plot is a tool used to introduce programming concepts, such as while and for loops, if/else/elseif, arrays, and others. Easy-to-understand explanations are followed with fun projects. I recommend this book for children ages ten and older who are interested in coding in a simple language.
