        I.             Introduction JavaScript is a powerful programming language that enables developers to build dynamic, interactive web applications. One of the key features of JavaScript is hoisting , a mechanism that allows variables and functions to be used before they are declared in the code . In this blog post, we'll explore the concept of hoisting in JavaScript and discuss its importance for creating effective and efficient code. Definition of hoisting: Hoisting is a mechanism in JavaScript that involves moving variable and function declarations to the top of their respective scopes during the compilation phase. This means that variables and functions can be used before they are actually declared in the code. However, only the declarations are hoisted, not the actual assignments or initializations, which may lead to unexpected behavior in some cases. Overview of how hoisting works During the ...

Method Overriding and Method Overloading in JavaScript.

Image
         I.             Introduction In object-oriented programming, there are two concepts known as method overriding and method overloading. These concepts allow developers to create more flexible and extensible code by providing different implementations of methods with the same name. Method Overriding Method overriding occurs when a subclass provides a different implementation of a method that already exists in its superclass. When the method is called on an instance of the subclass, the overridden method in the subclass is executed instead of the method in the parent class. Method overriding is a common practice in object-oriented programming, and is used to implement polymorphism. Method Overloading Method overloading is a feature that allows a class to have more than one method with the same name, but different parameters. When an overloaded method is called, the appropriate implem...
