Default exports

Instead of naming every function you want to import, you can alternatively import everything, and assign all of the imported items to a variable.

Instead of using object destructuring, import *, then, assign it to a variable using the as opertor. In our case, let's use an underscore (_), common with helper libraries.

import * as _ from './helpers.js';

// Get the total
let total = _.add(num1, num2);
