Solved: “Cannot use import statement outside a module” error — what was the fix?

I kept running into the “Cannot use import statement outside a module” error when using ES modules. Sharing this here—what steps helped you fix it, and are there better approaches to avoid this issue in the future?

This error occurs when JavaScript treats your file as non-module. The fix is to enable module support by adding "type": "module" in package.json or using <script type="module"> in HTML. You can also change .js to .mjs, or switch import to require() when using CommonJS.
