Echo JS 0.11.0

Classes in JS(ES6) are definitely sugar over the prototype chain... beyond this, you'll still need to have that inheritance chain for certain contexts.  If you choose prototype syntax over class syntax is entirely subjective.  I happen to think the class syntax is cleaner to look at and follow.

I don't think classical inheritance is a good use case for many types of workflows, for others, they are.  In general, where you want to persist state in conjunction with workflows, classes tend to work better.  Not that you can't work around them, but it really depends on your needs.

I tend to use classes very sparingly in JS.
