 Testing components that use React Router APIs is easiest with [`createMemoryRouter`][creatememoryrouter] or [`<MemoryRouter>`][memoryrouter] instead of the routers you use in your app that require DOM history APIs.
 
 Some of the React Router APIs internally use `fetch`, which is only supported starting from Node.js v18. If your project uses v17 or lower, you should add a `fetch` polyfill manually. One way to do that, is to install [`whatwg-fetch`](https://www.npmjs.com/package/whatwg-fetch) and add it to your `jest.config.js` file like so:

 ```js
 module.exports = {
-  setupFiles: ['whatwg-fetch'],
+  setupFiles: ["whatwg-fetch"],
   // ...rest of the config
-}
+};
 ```
