Summary of "Intro to Design Patterns | What, Why, Types | Explained in very easy way | Get your basics clear! ✌️"

The video introduces the concept of Design Patterns in software engineering, explaining their importance, types, and practical applications, especially in object-oriented programming (OOP). It emphasizes how Design Patterns help solve common coding problems related to creating, organizing, and managing interactions between classes, making code more scalable, reliable, and maintainable.

Main Ideas and Concepts

Challenge in OOP: While OOP concepts are taught, applying them effectively to write scalable, reliable, and maintainable code is not always straightforward.
Common Problems in Software Design:
- How to create classes and instantiate objects.
- How to organize classes into a coherent structure.
- How classes should interact with each other.
Design Patterns as Solutions:
- Design Patterns are proven, reusable templates or solutions to common software design problems.
- They are language-independent and can be applied in any OOP-supporting language.
- Widely used in daily work, interviews, and low-level design tasks.
Importance of Knowing Design Patterns:
- Helps in writing better code.
- Useful in job interviews, especially for system design questions.
- Not necessary to know all Design Patterns; focus on the most common ones.

Types of Design Patterns and Their Problems Addressed

Creational Design Patterns Focus: How to create objects and classes efficiently. Examples:
- Factory
- Abstract Factory
- Singleton
Structural Design Patterns Focus: How to organize classes and objects into larger structures. Examples:
- Bridge
- Adapter
- Composite
Behavioral Design Patterns Focus: How classes and objects interact and communicate. Examples:
- Interpreter
- Strategy
- Observer

Methodology / Next Steps Presented in the Video

The creator plans to release a series of videos covering widely used Design Patterns.
Each pattern will be explained with:
- The problem it solves.
- Why it is needed.
- Sample code demonstrations.
Viewers are encouraged to ask questions in the comments for further clarification.
