In ECMAScript 5, functions do triple duty: they are normal functions, methods and constructors. This is confusing, can lead to functions being used incorrectly and prevents normal functions from accessing the “this” of the surrounding scope.
ECMAScript 6 fixes the aforementioned problems by introducing more “callable entities”: arrow functions, classes and method definitions.
This talk explains what these callable entities are and how they fix the problems.
