#55 Destructuring and Default Values


Not really an ember tip but since ember uses ES2015 by default, it is somewhat related.

One of my favorite features in ES2015 (ES6) is object destructuring.  Imagine this code.

You can write the same code with:

c will be assigned 3 if it does not exist in obj.  There is a lot more to object and array destructuring – see links below for more tips.
