Importing other files

In your project you might want to split your code into multiple files.

This is a good practice to keep your code clean and easy to read.

Lets make another file called utils.js and write some code.

// utils.js
export const add = (a, b) => a + b

Now we can import the add function in our index.js file.

// index.js
import { add } from './utils.js'

console.log(add(1, 2)) // 3

When you run the index.js file you should see the number 3 in your terminal.

export keyword is used to export a function or a variable from a file. and import keyword is used to import a function or a variable from another file.
