[Behavioral 9] Strategy design pattern with TypeScript example

Key Advantages of this design pattern are (forgot to mention in the video):
1. Flexibility: Easily switch algorithms at runtime without changing the client code.
2. Open/Closed Principle: Add new strategies without modifying existing ones.
3. Encapsulation: Keep the algorithm implementation hidden from the client.
4. Clear code and easy usage;

Some popular use cases for the Strategy design pattern:
• Payment processing with multiple payment methods.
• Validation rules for forms.
• Compression strategies (e.g., ZIP, RAR, GZIP).
• Authentication.
