JavaScript Syntax question --- const { URL } = require('url');

In this case when initializing the file handling system in node.js the online documentation uses:

const fs = require('fs');  const { URL } = require('url');  const fileUrl = new URL('file:///tmp/hello');    fs.readFileSync(fileUrl);  

I am not familiar with the braces around the URL as in { URL }. What do they do here? On the previous line the fs is not surrounded with braces.
