What is CommonJS and how is it used in frontend development?

CommonJS is a module format that allows you to organize and reuse code in JavaScript. It's commonly used in Node.js but can also be utilized in frontend development to manage dependencies and modularize code.

Can you give me an example of how to use CommonJS in a frontend project?

Sure! You can create a file called math.js with functions like add and subtract, and then export them using module.exports. In your main file, you can import it using require('./math').

Are there any limitations to using CommonJS in the frontend?

Yes, one limitation is that CommonJS modules are loaded synchronously, which can lead to performance issues in the browser. Additionally, not all browsers support CommonJS natively, so you might need a bundler like Browserify.

What are some alternatives to CommonJS for frontend development?

Alternatives include ES Modules (ESM), which are natively supported in modern browsers, and AMD (Asynchronous Module Definition), which is designed for asynchronous loading.
