   @nilesh To utilize the ESM support in recent node.js releases, you either add "type": "module" to your package.json, or rename second.js to second.mjs.

     Here is the minimal version of my problem:

     In a fresh nodejs project (created via `npm init`), I have:

     `first.js` that has contents:

     ```
     export let x = 45;`
     ```

     And `second.js` that has:

     ```
     import { x } from 'first.js'
     console.log(x);
     ```

     Assume that I don't have the freedom to edit `first.js`. What do I need to do to make `node second.js` run correctly?

     I have tried almost everything that NodeJS suggests. How is rollup able to load and run such a file?

     I need Javascript help.

     I don't understand the Javascript module variants (ES / AMD / CJS / IIFE / UMD) at all. This trips me up every single time.

     I'm running a modern version of NodeJS (18.7.0). But why is it that the command `node_modules/rollup/dist/bin/rollup -c` works perfectly fine but running `node rollup.config.js` (or any other file using code like "import x from Y") throws a syntax error?

     How is rollup able to overcome a SYNTAX ERROR?
