Can you explain the difference between CommonJS and ES Modules?
Sure! CommonJS is a module system used primarily in Node.js, while ES Modules (ESM) is the standard for JavaScript modules in browsers and Node.js.
What are the main features of CommonJS?
CommonJS uses require()
to import modules and module.exports
to export them. It supports synchronous loading.
And how does ES Modules differ in terms of syntax?
ES Modules use import
and export
statements, allowing for asynchronous loading and better support for static analysis.
Are there any performance differences between the two?
Yes, ES Modules can be more efficient in browsers due to their asynchronous nature, while CommonJS can lead to blocking behavior.
