Design Patterns

Design patterns written in JavaScript and TypeScript.

Definition

A software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system.

In my opinion, this defines very well what a design pattern is.

Advantages of using them

• Promote easier changes
• Turns the objects reusable
• Keeps objects small and specialized

Types

• Creational patterns
• Structural patterns
• Behavioral patterns
• Concurrency patterns

Code examples

Type	Name	Information
Creational patterns	Builder	Go to detail 📄
Creational patterns	Singleton	Go to detail 📄
Structural patterns	Facade	Go to detail 📄
Behavioral patterns	Command	Go to detail 📄
Behavioral patterns	Null Object	Go to detail 📄

Another design patterns that I will add in the future:

• Factory
• Observer
• Decorator
• Strategy
• Adapter
• Iterator
• Proxy
• Composite
• Bridge
