Elm Language The Elm Architecture


The recommended way to structure your applications is dubbed 'the Elm Architecture.'

The simplest program consists of a model record storing all data that might be updated, a union type Msg that defines ways your program updates that data, a function update which takes the model and a Msg and returns a new model, and a function view which takes a model and returns the HTML your page will display. Anytime a function returns a Msg, the Elm runtime uses it to update the page.
