Node.js Module System vs ES6 Modules

What are the main differences between Node.js module system and ES6 modules?

The Node.js module system uses CommonJS syntax, while ES6 modules use the import and export syntax. CommonJS is synchronous and designed for server-side, whereas ES6 modules are asynchronous and can be used in both client and server environments.

Can you explain how to use ES6 modules in a Node.js application?

To use ES6 modules in Node.js, you need to set the type field in your package.json to module. Then, you can use import and export statements in your JavaScript files.

Are there any performance differences between the two module systems?

Yes, ES6 modules can be more efficient due to their static structure, allowing for better optimization by JavaScript engines. However, the performance difference may not be significant for most applications.

What about compatibility with older browsers?

Older browsers do not support ES6 modules natively. You may need to use a transpiler like Babel to convert your ES6 code to a compatible format.
