1. What are the key differences between TypeScript and JavaScript?
   TypeScript adds static typing and compile-time checks to JavaScript, enabling better tooling, error prevention, and refactoring.
2. How does TypeScript handle types in comparison to JavaScript?
   TypeScript allows both explicit and inferred typing, enabling developers to define types for variables, functions, and objects.
3. What are Union and Intersection types in TypeScript?
   Union types allow a variable to hold multiple types (string | number), while intersection types combine multiple types (TypeA & TypeB).
4. Explain interfaces vs. type aliases.
   Interfaces define object shapes and support extension, while type aliases are more flexible and can represent any type including primitives and unions.
5. How are generics used in TypeScript?
   Generics allow writing reusable and type-safe code, enabling components and functions to handle multiple data types.
6. What are access modifiers in classes?
   Access modifiers (public, private, protected) control the visibility of class properties and methods, enforcing encapsulation.
7. What are declaration files in TypeScript?
   Declaration files (.d.ts) provide type definitions for existing JavaScript code, enabling TypeScript to understand third-party libraries.
8. How does TypeScript integrate with React or Node.js?
   TypeScript can be configured in React using tsx files and works seamlessly with Node.js using ts-node or compiled output.
9. What are decorators in TypeScript?
   Decorators are annotations for classes and members that enable meta-programming, commonly used in Angular and advanced design patterns.
10. How can TypeScript improve debugging and code maintenance?
    With static type checks, intelligent tooling, and better refactor support, TypeScript reduces runtime errors and makes code easier to manage.
