How to access a global variable inside a module in TypeScript?

Hello everyone! I'm new to TypeScript and ran into a problem when transitioning from regular JavaScript to a module system. I have a project where I use a global variable `window.myApp` declared in a separate script (e.g., in `config.js`), which is loaded before my main module: ```typescript // config.js (loaded before modules) window.myApp = { apiBaseUrl: 'https://api.example.com', debugMode: true }; ``` In my TypeScript file, I'm trying to access this global variable, but TypeScript throws an error: ```typescript // main.ts import { fetchData } from './api'; const config = window.myApp; // Error: Property 'myApp' does not exist on type 'Window' console.log(config.apiBaseUrl); ``` I understand that TypeScript is strictly typed
