** Note: Updated for Elm 0.18
What is Elm?
Elm is an amazing new functional programming language for building Front End Web Applications.
Elm was designed as an answer to the following question:
"What would be a good language for building front end web apps?"
Elm has been thoughtfully crafted over the last several Years by it’s creator Evan Czaplicki, adding just enough features to make it powerful but still simple to use.
Elm, unlike most other functional programming languages, achieves a nice balance between Idealism and Pragmatism.
Why should you consider using Elm?
Benefits such as:
- Zero Runtime Exceptions
- Simplified Debugging
- Easy Refactoring
- Helpful Type System & Compiler
- Improved Productivity
- Inherently testable code
- Enforced Semantic Versioning
- and more...
Personally, I like Elm because it makes my life Simpler, it’s a Joy to use and I’m just more productive.
"I’ve tried to learn functional programming before, but ..."
If you’ve ever dabbled in a functional programming language, or tried to learn functional programming but became frustrated by the learning curve, let me tell you things are different with Elm.
You won’t see a bunch of scary academic terms in the Elm documentation or from hear it from the Elm community.
Elm is very approachable, and is the best language to learn functional programming.
"Should I learn elm if I can’t use it at work?"
Even if you never use Elm Professionally in your Job, it’s still totally worth learning.
You’ll gain functional programming skills that you can take back to your imperative languages... However you may find that Elm is so nice, you may just become the advocate that persuades your employer to start using it at work ;)
What we’ll build
After you learn the basics, we’ll build a portion of a Realtime Basketball Scorekeeping App. Specifically we’ll create a prototype of the Scorekeeping interface, turning a mockup into a working app.
"What am I going to get from this course?"

Just did my first #elm-lang app with @uknowthen's free elm course for beginners :) It's great and you should take a look :)

James discovered the joy of software development while submerged hundreds of feet deep in the pacific ocean. He liked it so much, he left his career as Navy Nuclear Submariner to learn everything he could about creating software. As a nuclear trained engineer, he figured out how to learn things quickly, which has helped in a career where the learning never stops. Currently he’s an independent software developer, consultant and trainer.
