If you haven't already created a lib directory, you can do that by running:
Now let's create some some coffeescript code file, we'll call it typed-implementation.coffee that will perform the 'typing':
And then call it right below the call to the typed.js library in the application.js file:
Now, all we have to do it add a new span tag that contains the element class that our Coffeescript code is looking for:
And you should now have a great looking 'typed' element on your site!
