 #### `response.body`
 
 Nodejs has two kinds of streams: [web streams](https://nodejs.org/dist/latest-v16.x/docs/api/webstreams.html), which follow the API of the WHATWG web standard found in browsers, and an older Node-specific [streams API](https://nodejs.org/api/stream.html). `response.body` returns a readable web stream. If you would prefer to work with a Node stream you can convert a web stream using `.fromWeb()`.
 
 ```js
-import { fetch } from 'undici';
-import { Readable } from 'node:stream';
+import { fetch } from 'undici'
+import { Readable } from 'node:stream'
 
 const response = await fetch('https://example.com')
-const readableWebStream = response.body;
-const readableNodeStream = Readable.fromWeb(readableWebStream);
+const readableWebStream = response.body
+const readableNodeStream = Readable.fromWeb(readableWebStream)
 ```
