Summary
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!

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the technology
Simply put, the Elm programming language transforms the way you think about frontend web development.

Elm’s legendary compiler is an incredible assistant, giving you the precise and user-friendly support you need to work efficiently. Elm applications have small bundle sizes that run faster than JavaScript frameworks and are famously easy to maintain as they grow. The catch? Elm isn’t JavaScript, so you’ll have some new skills to learn.

About the book
Elm in Action teaches you the Elm language along with a new approach to coding frontend applications. Chapter by chapter, you’ll create a full-featured photo-browsing app, learning as you go about Elm’s modular architecture, Elm testing, and how to work seamlessly with your favorite JavaScript libraries. You’ll especially appreciate author and Elm core team member Richard Feldman’s unique insights, based on his thousands of hours writing production code in Elm. When you’re done, you’ll have a toolbox of new development skills and a stunning web app for your portfolio.
