elm command [options]

elm is the command-line tool for the Elm programming language, a functional language for frontend web development. It handles project initialization, compilation, package management, and development tools.
Elm compiles to JavaScript with no runtime exceptions through its strong type system. The compiler provides friendly error messages that help fix issues.
The reactor provides a development server with hot reloading, while repl offers interactive Elm evaluation.
