The ./src/script.js file will be compiled through Webpack.
In production, the final code will be split into two files: one for all the vendor dependencies, and one for this website-specific code.
Doing so allows for faster loading both in dev and in prod as you won't change your dependencies as often as your custom code, so only one file needs to be downloaded/generated again.
Filenames will also be revved, so any change to the content of either file will be available on a new url; bypassing any cache.
You can change the file to use as the entrypoint through the js.input key of
the norska.config.js file. Default is script.js.
If you're creating your own custom layout, you should use the norska_scripts mixin to properly include all the needed files to your HTML.
