How can I use TypeScript with JavaScript modules?

You can use TypeScript with JavaScript modules by ensuring your TypeScript configuration allows for module resolution. You can set the module option in your tsconfig.json to commonjs, es6, or another module system depending on your needs.

What do I need to include in my tsconfig.json file?

In your tsconfig.json, you should include properties like compilerOptions, where you can specify module, target, and outDir. For example:

{
  "compilerOptions": {
    "module": "es6",
    "target": "es5",
    "outDir": "./dist"
  }
}

Can I import JavaScript files directly in TypeScript?

Yes, you can import JavaScript files directly in TypeScript. Just ensure that the JavaScript files are in the same directory or a specified path, and TypeScript will handle the imports.

What about type definitions for JavaScript modules?

For JavaScript modules, you can use DefinitelyTyped to find type definitions. You can install them using npm, for example: npm install --save-dev @types/module-name.
