Clean Code Practice

• S - Single-responsibility Principle
• O - Open-closed Principle
• L - Liskov Substitution Principle
• I - Interface Segregation Principle
• D - Dependency Inversion Principle

• Class should have one and only one reason to change, meaning that a class should have only one job.
• Function, as a class should perform just one action, and implement one logic Open-closed Principle (OCP), states:
• Objects or entities should be open for extension but closed for modification.
• This means that a class should be extendable without modifying the class itself.
