What are ES6 modules and how do I use import and export?

ES6 modules are a way to structure JavaScript code by splitting it into separate files. You can use the import statement to bring in functions, objects, or primitives from another module, and the export statement to make them available for use in other modules.

Can you show me an example of how to export a function?

Sure! You can export a function like this:

// myModule.js
export function myFunction() {
  console.log('Hello from myFunction!');
}

And how do I import that function in another file?

You can import the function using the following syntax:

// main.js
import { myFunction } from './myModule.js';
myFunction(); // This will log 'Hello from myFunction!'

What if I want to export multiple functions?

You can export multiple functions by listing them in the export statement:

// myModule.js
export function functionOne() { ... }
export function functionTwo() { ... }
