JSFoo: round the year submissions

It is a long time debate that whether JavaScript is an Object Oriented Language or not? We all know that it is not, then how almost everything in JavaScript is an object. If we do not have class (yes in ECMA 6, there is a keyword class syntax introduced but that is not a real class anyway) then how objects are created?
Answer of all above questions lie in understanding of following concepts,

• Different ways of JavaScript object creation
• prototypes and prototype chain
• this keyword
• proto

JavaScript objects are much more than what you see in an object literal. In addition, above concepts are pivotal, because they are foundational to do real programming with JavaScript.
This session will simplify these backbone topics of JavaScript language. As a starter, JavaScript is a prototype based language in which object is created by another object, and in order to do that it creates a prototype chain. Having a good understanding of prototype is required to write real JavaScript applications or to work effectively with popular JavaScript Frameworks.
