What are the differences between ES6 imports and CommonJS require?

ES6 imports are part of the ES6 module system, while CommonJS require is used in Node.js. ES6 imports are static and can be optimized by the compiler, whereas CommonJS is dynamic and executed at runtime.

Can you give me an example of how to use both?

Sure! For ES6, you would use import { myFunction } from './myModule.js';. For CommonJS, it would be const myFunction = require('./myModule');.

Are there any performance differences between the two?

Yes, ES6 imports can be more performant due to static analysis, allowing for tree shaking and better optimization during bundling.

Which one should I use in my project?

If you're working with modern JavaScript and tools that support ES6, go with ES6 imports. For Node.js projects, CommonJS is still widely used, but ES6 is becoming more common.
