Import not working with JavaScript in PhpStorm/Webstorm

I’m trying to run a piece of JavaScript code written in a tutorial that looks like this:

main.js

import Vue from 'Vue';
import Alert from './components/Alert.vue';

new Vue({
    el: 'body',

    components: { Alert }
})

However, PhpStorm is giving the following error:

Import declarations are not supported by current JavaScript version

How I can get a newer(?) JavaScript version in PhpStorm? Is that really the problem here?

Answer

In your preferences, change the version of javascript to ECMAScript 6.
