What is Object-Oriented Programming?
Object-Oriented Programming (OOP) is a programming paradigm that organizes code into reusable objects. These objects are instances of classes, which encapsulate data (properties) and behavior (methods). OOP promotes modular design, code reusability, and enhances the overall maintainability of the codebase.
class keyword. They serve as blueprints for creating objects with predefined properties and methods. The class-based approach allows for easy instantiation of multiple objects with similar characteristics.
Constructors: Constructors are special functions that are used to create new instances of objects. They define how an object should be initialized when created using the
new keyword. Constructors can also define properties and methods that are shared by all instances of a class.
Prototype Chain: The prototype chain is a hierarchical structure that enables objects to access properties and methods defined in their prototype or parent objects. This mechanism allows for code reuse and promotes a more efficient use of memory.
Method Overriding: Method overriding occurs when a subclass provides its own implementation of a method that is already defined in its parent class. This allows for customization and modification of inherited behavior.
Closures: Closures allow variables to be declared outside of an object’s scope but still accessible within its methods. This helps to achieve data privacy and encapsulation by preventing direct access to internal variables.
Naming Conventions: By using naming conventions such as prefixes or underscores (_), developers can indicate which properties or methods are intended to be private or internal, signaling that they should not be directly accessed from outside the object.
