Creating Modular Code in Node.js Using Classes
In Node.js, the class keyword is used to create a blueprint for objects, supporting object-oriented programming principles such as encapsulation, inheritance, and polymorphism. Classes contain properties and methods and can be instantiated to create multiple objects. Node.js classes allow developers to structure code in a more modular and maintainable way, improving readability and reusability. A class can have a constructor, which initializes object properties, and methods, which define object behaviors. Additionally, inheritance enables a class to inherit properties and methods from another class, promoting code reuse and the DRY (Don't Repeat Yourself) principle.
This code defines a Person class with a constructor and a greet method. The Student subclass extends Person, adding a studentID property and a getStudentDetails method. An instance of Student is created, and its details are logged.
