Learning Elm From A Drum Sequencer (Part 2)

In part one of this two-part article, we began building a drum sequencer in Elm. We learned the syntax, how to read and write type-annotations to ensure our functions can interact with one another, and the Elm Architecture, the pattern in which all Elm programs are designed. In this conclusion, we’ll work through large refactors by relying on the Elm compiler, and set up recurring events that interact with JavaScript to trigger drum samples.
