Our very first CoffeeScript code
Let's open up a CoffeeScript console. We saw earlier that Node provides a console to interactively run JavaScript code. You guessed it, the CoffeeScript console works the same way, but with CoffeeScript!
coffee
coffee> subject = "World"
'World'
coffee> "Hello, #{subject}!"
'Hello, World!'Don't worry about the syntax for now. We'll get to that soon. When you're finished, hit Ctrl + D to close the console, and take a moment to bask in the glow of a properly configured development environment.
