Class vs Object

Class

A class is a blueprint for creating objects. It defines variables and methods that represent the structure and behavior of a specific object.

Object

An object is an instance of a class. When a class is instantiated, it becomes an object in memory. In the analogy of a car, a class is like the blueprint or design of the car, and an object is the actual, tangible car created based on that blueprint. Creating an object from a class is done using the new keyword.

Procedural vs Object-Oriented Programming

Procedural Programming

• Processes tasks in a step-by-step manner.
• C language is a representative example.
• Similar to the computer's processing structure, leading to fast execution.
• Maintenance can be challenging.

Object-Oriented Programming

• Considers data and procedures as a single unit.
• Encapsulation: Data and algorithms (code) are grouped into a single unit.
• Inheritance: Allows the creation of a new class by inheriting from an already existing class.
• Polymorphism: One name (method) can be used for various situations.

💡 It's not always about using only object-oriented languages; there are pros and cons depending on the situation.

Function vs Method

Function

• A code snippet that performs a specific task.
