What are the differences between CommonJS and ES Modules in React?

CommonJS is a module format used in Node.js, while ES Modules (ESM) is the standard for JavaScript modules. In React, ESM is preferred for its static structure and support for tree-shaking.

Can you explain how to use ES Modules in a React project?

To use ES Modules in a React project, you can use the import and export syntax. For example, you can export a component like this: export default MyComponent; and import it in another file using import MyComponent from './MyComponent';.

Are there any compatibility issues I should be aware of?

Yes, some older browsers may not support ES Modules natively. You can use tools like Babel to transpile your code for compatibility.

What about using CommonJS in React?

While you can use CommonJS in React, it's generally not recommended for front-end code due to its dynamic nature, which can hinder optimizations like tree-shaking.
