Answer 3

You're importing a polyfill that is not included by default. You have to install it as a dependency first. How to do that is in a comment on the same line that imports it:

// Run `npm install --save classlist.js`.

The same goes for the web-animations-js polyfill if you haven't done so already.

Answer 4

Run the following commands in terminal/command prompt:

1. npm install --save classlist.js
2. npm install --save web-animations-js
