I can't remember the example I used in the meeting, but one example is a recursive function: class Chicken extends Weapon { constructor(length, elasticity, initialVelocity) { this.length = length; this.elasticity = elasticity; this.initialVelocity = initialVelocity; var self = this; function animate() { ... self.velocity self.elasticity self.length ... setTimeout(animate, n); ... } ... } } The point I was making in the meeting was that arrow functions are a syntactic convenience for a common case, not a general-purpose replacement for all functions that need to refer to an outer this-binding. They are not general-purpose because they don't support all the features of longhand functions.
