FAQs About JS Modules
Modules are reusable pieces of code stored in separate files, enabling import and export functionalities.
Named Exports: Export multiple values by name.
Default Exports: Export a single primary value, which can be imported with any name.
Modern browsers support ES6 modules. Older browsers may need tools like Babel.
Dynamic imports enhance performance by loading code only when needed.
ES6 modules are statically analyzed with import/export, while CommonJS uses require and is dynamically executed.
