Write a blog about objects and its internal representation in Javascript.

Objects:-
    Object is an entity that defines own property and it's value for example In Real Life 
A Person is an example of an Object cause a person contain the properties like Name,Age,Eye-color
etc.. and also those properties have their values like "john",5,"brown" we can define these as an
objects

Objects in Javascript:
    In JavaScript, almost everything is an object
    Booleans, Numbers, Strings, Dates, Maths, Regular expressions ,Arrays ,Functions 
    Objects are variable too but objects can contain many values
    
    It is one of the most important DataType in JavaScript and it is different from 
    primitive DataType(Booleans, Numbers, Strings,Null and undefined)

    objects in JavaScript may be defined as an unordered collection of related data, of primitive or 
    reference types, in the form of “key: value” pairs 
        ex: like the person we mentioned above 

Objects are variable:
    in JavaScript objects are variable too but can contain many values and key value pair 
    let name = "jhonwick"
    here the Variable name value is defined as single property value 

    if we define as an object refered to it's property-name and value and Property name are case sensitive 
        ex : let person = {firstName:"Jhon", lastName:"Wick", age:50, eyeColor:"blue"};
        person => object,
        firstname=> property-name 
        value=> "jhon"
    we can define a different properties with different datatype 
    Unassigned properties of an object are undefined (and not null).
    person.DOB => undefined

objects Methods:
    Object Method can be refered/accessed with two methods 
        i) .(dot)method
        ii) [](Box)method
    Iterate:
        The iterator protocol defines how to produce a sequence of values from an object
        using (for of/in)Methods
        You can use the bracket notation with for...in to iterate over all the enumerable properties of an object

        Example representation in Javascript
                let person = {
                                firstName: "Jhon",
                                lastName: "wick",
                                age:50,
                                eyeColor:"blue"
                                };
                console.log(person.firstName) 
                            or
                console.log(person['firstName'])
    Objects obove represent as object=> person
                               Property-name=> firstName(Case-sensitive)
                               property-vale=> Jhon
