Design Patterns in JavaScript

Just started course, Design Patterns in JavaScript on Udemy.

Here is summary from first section by @nesteruk from course.

Single Responsibility Principle

• A class should only have one reason to change
• Seperation of concerns -> different classes handling different, independet tasks/problems

Open-Closed Principle

• Clases should open for extensions but closed for modification

Liskow Substition Principle

• You should be able to substitute a base type for a subtype

Interface Segragation Principle

• Don't put too much into an interface; split into separate interfaces
• YAGNI - You Ain't Going to Need It

Dependency Inversion Principle

• High-level modules should not depend upon low-level ones; use absractions
