Elm is more than just a cutting-edge programming language, it''s a chance to upgrade the way you think about building web applications. Once you get comfortable with Elm''s refreshingly different approach to application development, you''ll be working with a clean syntax, dependable libraries, and a delightful compiler that essentially eliminates runtime exceptions. Elm compiles to JavaScript, so your code runs in any browser, and Elm''s best-in-class rendering speed will knock your socks off. Let''s get started!

Elm in Action teaches you how to build well-designed, highly performant web applications using the Elm language. As you read, you''ll follow an application called Photo Groove that will show you how to structure your application''s domain and behaviour, how to maintain a pleasantly modular architecture, and how to deliver a quality product using the Elm language. Along the way, you''ll learn how to interact smoothly with browser functionality, servers, and JavaScript libraries, as well and picking up a few tricks for building fluid, intuitive user experiences. If you''re new to functional programming, you''ll also gain a practical understanding of techniques that will make you a better developer no matter what you''re writing!

Written for readers comfortable with web application development in JavaScript. No experience with Elm or functional programming required.
