In this course, you begin with an introduction to Ember.js, a JavaScript framework for building client-side applications.

After that, the course guides you through the steps of building a real application so that you can see how the concepts are applied in practice. You'll learn about the building blocks of Ember one by one, in a way that crushes the allegedly steep learning curve of the framework.

The application will get shinier (and/or more robust) with each chapter. By the end, we will have a decent app, and you'll have a great new skill you can add to your resume.

Developing Robust Ember.js Applications

## Problem statement 
We have to count the number of words in the band descriptions so that people don’t write novels. We also want to show them how many words they’ve written. Write a template helper called `words-in` that counts the words in a string passed to it.  Whitespace and punctuation are not considered words, and empty values, including null and undefined, should be considered as having a length of zero.


## Coding exercise
Write your code below. I recommend that you try solving the exercise yourself before viewing the solution.

Good luck!
