TypeScript brings several powerful features to JavaScript development, which help in creating safer, more maintainable, and scalable code. Here are some key features of TypeScript:
Static Typing: TypeScript introduces static typing, providing type checking during the development stage rather than at runtime. This leads to early detection of errors and better developer tooling.
Interfaces: Interfaces define the shape, structure, and contract of objects or classes, allowing for custom types and enforcing a consistent structure across your codebase.
Classes: TypeScript supports object-oriented programming concepts like inheritance, encapsulation, and abstraction through classes and their related features, such as constructors, access modifiers, and abstract classes.
Generics: Generics enable you to create highly reusable and flexible components that work with a variety of types without sacrificing type safety.
Type Inference: TypeScript automatically infers types of variables and expressions when they are not explicitly specified.
