Tell us about projects where you used TypeScript, and describe their features.

I have used TypeScript in several projects where strict typing and scalable code in Node.js were required.

Features of such projects:

• Improved support for autocomplete and refactoring thanks to static typing.
• Ability to use modern JavaScript features with type checking.
• Compilation to plain JavaScript, ensuring compatibility across different runtime environments.
• Often used in backend services with Express.js, where model and request types help avoid errors.

Example of usage:

interface User {
  id: number;
  name: string;
}

function getUser(id: number): User {
  return { id, name: "John" };
}
