Design Patterns

“Design patterns are very useful when we study how they work so we can create similar patterns. They are bad when we try to copy them directly.”

(Anonymous)

The above quotes tells both it's significant if understood & implemented correctly & at the same time it can lead to the disasters if the need is not identified & the wrong pattern is used. The design pattern is always a topic of discussion in interviews, conferences, podcasts, software design approaches. There were 30+ patterns. All were mainly categorized into 3 categories:

• Creational patterns: Provide the way to create an object or series of objects by hiding the object creation implementation.
• Structural patterns: It establishes the relationship between the classes & objects. It highly uses inheriance & composition.
• Behavioral patterns: This completely focuses on how objects communicate with each other.
