Inheritance in JavaScript allows a class to inherit properties and methods from another class. This is a fundamental concept in object-oriented programming (OOP) that promotes code reusability and logical hierarchy. It helps in creating a parent-child relationship between classes. In JavaScript, inheri...
classClassName{ //class body } Creating a Class in JavaScript In programming, a class can be seen as a generalized entity that is used to create a specialized object. For example, in a school environment, a generalized entity (a class) can be students and an object of students can be J...

JavaScript statements control the overall flow of JavaScript programs. Statements are used to declare variables and manage iterative processes, and they can also be used to declare classes and functions. Unlike properties, methods, and events, which are inseparable from the object that owns them, st...
Declare Multiple Variables in a Single Line Using De-structuring Algorithm in JavaScript With the introduction of ES2015 (also known as ES6), the de-structuring algorithm was added to JavaScript, and it has quickly become one of the most valuable aspects of the language for two reasons: ...
It can be marked as ‘abstract’ even if it doesn’t declare any. If an abstract class lacks method implementations entirely, it’s advisable to consider using an interface. Java doesn’t support multiple-class inheritance. Subclasses of an abstract class in Java must implement all the ...
