 The `URLSearchParams` API provides read and write access to the query of a
 `URL`. The `URLSearchParams` class can also be used standalone with one of the
 four following constructors.
+The `URLSearchParams` class is also available on the global object.
 
 The WHATWG `URLSearchParams` interface and the [`querystring`][] module have
 similar purpose, but the purpose of the [`querystring`][] module is more
 general, as it allows the customization of delimiter characters (`&` and `=`).
 On the other hand, this API is designed purely for URL query strings.
 
 ```js
-const { URL, URLSearchParams } = require('url');

 const myURL = new URL('https://example.org/?abc=123');
