Objects in Javascript

                                          var person = {
                                            firstName:"John",
                                            lastName:"Doe",
                                            age:50,
                                            eyeColor:"blue"
                                        };
                                        
                                        

J avaScript is designed on a simple object-based paradigm. An object is a collection of properties, and a property is an association between a name (or key) and a value. A property's value can be a function, in which case the property is known as a method.
