TL;DR

Elm is also a programming language with an interactive shell. Let’s introduce Repl.  This post is part of the functional language series.

If you expected a detailed “guide by the hand” tutorial, you are wrong. I found the software testers are brilliant people. Now you know that Elm has an interactive shell, play with it. I found that explaining how to exit something is a waste of paper or bits. However, almost every book does it. If you can not figure out how to exit repl, you do not understand English.

Try help or calculation operations. Try to create a list of something. You must learn how to use repl for running your UNFINISHED programs. This would be the first step. Using repl, you can run your new function very quickly. Or somebody else’s functions! Isn’t this exciting!
