JavaScript for Kids is a lighthearted introduction to the JavaScript language and programming in general. With the help of kid-friendly examples, author Nick Morgan teaches the essentials of JavaScript. Morgan starts with the basics of strings, arrays, and loops, then moves on to show readers how to modify elements with jQuery and draw graphics with canvas. By the end of the book, you'll be ready to create your own fun animations and games and you'll have a solid understanding of the fundamentals of JavaScript.
