What TypeScript design patterns are often used in large-scale applications?
The question is about TypeScript .
Common TypeScript design patterns for large projects include Singleton (maintains a single instance of a class, useful for settings or logging), Factory (creates objects dynamically to reduce dependencies and enhance flexibility), and Decorator (adds extra functionalities like caching or logging to classes or methods without modifying their core code). The Observer pattern enables event-driven programming where one object's update notifies others. Dependency Injection supplies required components to classes from outside, making code more modular and testable. These patterns help TypeScript apps stay organised and maintainable as they grow.
