Q1: Explain equality in JavaScript ☆

Answer: JavaScript has both strict and type–converting comparisons:

Strict comparison (e.g., ===) checks for value equality without allowing coercion
Abstract comparison (e.g. ==) checks for value equality with coercion allowed

	1. Write poly-fill of Object.create and explain why it worked:

	if(typeof Object.create != "function") {
	Object.create = function(param) {
	var Fun = function(){};
	Fun.prototype = param;
	return new Fun();
	}
	}
