ES6 fat arrows provide reasonable `this` behaviour, which protects us from some subtle accidental bugs, and erradicates `const self = this` from the codebase. Far arrows were not applied in Mocha code and AngularJS controllers/services constructors since these frameworks rely on `.bind()` on those functions.
