Can you tell about projects where you used TypeScript?

In projects using TypeScript, I employed this language for developing server-side logic on Node.js and frontend applications. TypeScript helps improve code quality through static typing and autocompletion. For example, in one project, I wrote a REST API using Express and TypeScript, which helped avoid many errors during compilation and simplified code maintenance.

Here's an example of a simple controller in TypeScript:

import { Request, Response } from 'express';

export const getUser = (req: Request, res: Response): void => {
  const userId: string = req.params.id;
  // logic to retrieve user
  res.json({ id: userId, name: 'Ivan' });
};
