Arrow functions

List of features (non-exhaustive)

Disallows global variables. (Catches missing var declarations and typos in variable names)

An event is a signal that something has happened. All DOM nodes generate such signals (but events are not limited to DOM).

To react on events we can assign a handler – a function that runs in case of an event.

Event Capturing and Event Bubbling allow us to implement one of most powerful event handling patterns called event delegation.

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.
