# Aliases on import in JavaScript

You can rename functions on import. This is done with the `as` command. For example, let's rename the `root2` function to `sqrt` function:

`import {root2 as sqrt, root3} from './math.js';`

Let's check the code:

`let res = sqrt(2) + root3(3); console.log(res);`

When importing your module, rename the `pow2` function to `square` and the `pow3` function to `cube`.
