  1. DI.
  2. Clear separation of concerns.

I believe that writing testable Javascript has been possible since the name Javascript was invented. Angular.js has made it easier by doing its best to force you to write testable code.

you can use DI in backbone and clearly seperate your concerns as well. It is just not as much enforced in the framework (not opinionated)
