Elm is a programming language that lets you write web apps in the browser.

In this book I will be showing you how to build a calculator step by step using Elm.

It is expected that you know a little bit about web programming like HTML, CSS, and JavaScript. If you are new to web programming that is OK. Elm is a great way to start web programming.

If you already know Vue.js or React and are curious about Elm, this is also a great place to start learning Elm. As a programmer, learning Elm has made my JavaScript code better.


This book uses the latest version of Elm 0.19


Things covered in this book are

- CSS with an external style sheet

- use Elm's type system to eliminate bugs

- use elm-live as s development server

- custom keyboard input events (including key combo events like alt-shift-delete)

- testing with elm-test and elm-program-test

- deploy the app with Netlify

The example application can be found live at https://elm-calculator.netlify.com/
