 With the split the CommonJS and ESM module systems, runtimes and bundlers need a way to determine what type of module system your `.js` files are using. Because CommonJS came first, that is the default - but you can change it by adding `"type": "module"` to your `package.json`, which then means that your `.js` files will be viewed as ESM modules.
