Design Patterns in System Design

Design patterns are typical solutions to common problems in software design. Each pattern is like a blueprint that you can customize to solve a particular design problem in your code.

In this module, we explore how low-level design patterns (like those from the Gang of Four) evolve into high-level system architectural patterns as applications scale.

Key Topics

• Connecting System Design with Design Patterns
• Observer Pattern vs. Pub/Sub Systems
• Scalability through Decoupling
• Real-world Examples in JavaScript
