Demonstrating closure for Encapsulation in javascript:functioninitializeData() {varmyVar =1;return{getVar:function() {returnmyVar; },setVar:function(value) { myVar = value; } }; } obj =initializeData();document.write("Initial value of variable: "+ obj.getVar() +""); obj.setVar(2);docum...
Encapsulation: Constructors can enforce encapsulation by setting the data members of the class to private and providing public constructors to create and initialize the object. It helps in protecting the data contained within the object from external manipulation and ensures that the object is always...
object-oriented programming is a programming paradigm that is based on the concept of objects, which are data structures that contain data and code to manipulate that data. object-oriented programming is based on the principles of encapsulation, inheritance, and polymorphism. encapsulation refers to ...
