What are the compatibility issues with ES modules in Node.js?

Node.js has had some challenges with ES module compatibility, especially with older versions. Key issues include differences in how modules are imported and exported, and the need for specific file extensions.

Can you explain how to use ES modules in Node.js?

To use ES modules in Node.js, you can either set the 'type' field in your package.json to 'module' or use the .mjs file extension. This allows you to use 'import' and 'export' syntax.

Are there any performance differences between CommonJS and ES modules?

Yes, ES modules can offer better performance due to static analysis, which allows for tree-shaking and more efficient bundling. However, the differences may vary based on the specific use case.

What should I do if I encounter an error while using ES modules?

If you encounter an error, check your import/export syntax, ensure you're using the correct file extensions, and verify that your Node.js version supports ES modules.
