Install Elm from the official site or via npm, then verify with the command line. Configure your editor, explore the built-in repl, reactor, and package manager to start tinkering.
Install elm format by downloading, unzipping, and placing the executable in your system path, then test by typing format --help in the command line.
Learn how records with key-value pairs and mixed types enable structured data, then use a type alias as a constructor to enforce a fixed format for user records.
Explore pattern matching on records in Elm to extract needed fields, like user id, and branch logic with compile-time guarantees, avoiding missing fields and the this keyword, unlike JavaScript objects.
Learn how to write Elm files, declare a module, and use the Html package to render text, then compile to Html or JavaScript and embed into the DOM.
Learn Elm programming by implementing a size checker to prevent shrinking below one, and adding or removing exclamation marks with a string checker and union types.
Learn to build a beginner-friendly Elm word guessing game by constructing a simple model, messages, update logic, and view with input and live feedback.
Refactor the Elm model by grouping revealed word and position into a dedicated record, enabling safer reveal and increment logic and cleaner data handling.
Refactor code in Elm by introducing type aliases and records for revealed word and result, replacing brittle string matching with typed data and updating the model to reflect correct results.
Learn to filter the word list in elm by excluding the word from the model. Use filter with an anonymous function, and list drop, plus piping and list take one.
Explore the Elm HTML program feature by building a simple mouse-click tracker that uses subscriptions to mouse events, updating x and y coordinates in the model.
Expand the chat app by prompting for a user name on load with validation, sending it to the server to format messages, and adding a server-side time feature with moment.
Wraps up the beginner's Elm programming course with encouragement to build simple apps, practice hands-on coding, read official docs, and solidify the basics to build web apps.
"This is a great course if you start with ELM. Good tips, about setting up environment. Very simple explanation of a problems you can come across in ELM. I love examples, not just one application but multiple use cases, also thanks for now showing us to do list or counter (because in real life that is what we build ;) all day long)." - Maciej P.
"It's a really great progression through concepts. It feels like you're working through the required thought processes to build up functionality from scratch. I have no doubt that I can follow the same reasoning for new projects and have little trouble making everything work. Also does a great job of showing off the most powerful and useful features of Elm early on, to encourage progression." ⭐ ⭐ ⭐ ⭐ ⭐

Do you want to learn to make web apps? Enroll in Mammoth Interactive's Beginner's Guide to Elm Programming. Build Web Apps!
In this course, web developer Chris Veillette will teach you how to code in the Elm language to build real websites and apps.
What is Elm?
Elm is a programming language that you can use to build web apps. Elm is user-friendly, which makes it a great place to learn to build web apps.
Elm is a functional language that compiles to JavaScript. It is a separate language from JavaScript, which means you must learn the syntax and language rules of Elm.
What are the advantages of Elm?
Elm allows you to write well-architectured code that is easy to read.
Elm makes front-end development simpler.
Elm provides light operations, which means it involves less fatigue than JavaScript. With JavaScript-heavy apps, a lot of tooling and frameworks can be required to make a simple app. Elm provides a lighter operation by being self-contained.
Elm comes with creative built-in tools, meaning you don't have to download other packages
Elm is easy to understand and use once you learn the language
There is a supportive community with an active creator (Evan Czaplicki)
Elm has no runtime exceptions, which can occur in JavaScript. Instead Elm gives you warning messages.
Elm's warning messages are in a readable language
Elm's built-in package manager protects code from minor errors
And more!
You can learn to build websites and apps in Elm. Get started with this up-and-coming programming language.
The course can be summed up as lots of walkthroughs.
This course is full of practical examples. We teach you theory while also building real projects that you can put in your web development portfolio.
"Very good introductory course on Elm-lang and functional programming."
"This course does a great job of presenting the material in small easy to process chunks and the author does a great job explaining everything in a easy to understand way."
