With new features, language improvements, paradigms, and potential use cases appearing regularly, there’s never been a more exciting time to be a JavaScript developer.  

In The Joy of JavaScript, author and JavaScript expert Luis Atencio teaches you key design concepts that lead to clean, lean, modular, and easy-to-maintain code.
