Classes are the cornerstone of Object-Oriented Programming in modern JavaScript, providing a clear and concise syntax for modeling real-world entities.
1The Class Structure
A class serves as a template. The constructor is the most vital part, as it sets the initial state of every object created from that class. Inside a class, you can define methods that represent the actions the object can perform. By using the new keyword, you instantiate these templates into living objects in memory.
2Inheritance & Privacy
Inheritance through the extends keyword allows you to create specialized versions of existing classes. The super keyword ensures that the parent class's logic is preserved. For security and stability, modern JS introduced private fields (using the # prefix), allowing you to hide internal implementation details from the rest of the application.
