| Sumario: | Among today’s frontend technologies, the Elm programming language is genuinely unique. Lightweight and easy to work with, Elm is a functional language that compiles to JavaScript with code that’s fast, hard to break, easily testable, and extremely maintainable. In this report, author Matthew Griffith provides a quick overview of Elm with emphasis on its advantages over JavaScript and other popular frontend frameworks. Created specifically for the web frontend, Elm eliminates many of the most common pain points of frontend development. Runtime exceptions are practically nonexistent, and refactoring is largely painless because of the strength and user-friendliness of Elm’s compiler. This report explains how you can adopt Elm into your projects incrementally.
