I'm trying to import myArr from hello.js into index.js. However I get an error of
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module File hello.js
export let myArr = ['hello', 'hi', 'hey']; File index.js
import { myArr } from './hello.js'; console.log(myArr); Where am I going wrong?

To be able to load an ES module, we need to set “type”: “module” in this file or, as an alternative, we can use the . mjs file extension as against the usual . js file extension. Also, from Node version 12.7.
// ⛔️ To load an ES module, set "type": "module" in // package. json import moment from 'moment'; moment(). format(); To be able to load ES modules, set the type property to module in your project's package.
Use version 2:
npm install node-fetch@2 node-fetch from v3 is an ESM-only module - you are not able to import it with require().
If you cannot switch to ESM, please use v2 which remains compatible with CommonJS. Critical bug fixes will continue to be published for v2.

I ran your code without any problems. Check for two things:
package.json includes a line for "type": "module". Without this line, Node.js assumes you want to use CommonJS modules rather than ESM.
