Job listing with Filtering using ArrowJS

[jeanwl]

I used a Frontend Mentor project to try ArrowJS.
Github project: https://github.com/jeanwll/static-job-listings-master
Live site: https://jeanwll.github.io/static-job-listings-master/

I am very happy about the result and ArrowJS usage.

I used Class for components, what do you think about this?

I noticed a inconsistent behaviour;
Returning false from an attribute static expression will NOT remove the attribute but simply return false:

<li data-featured="${false}"> // returns <li data-featured="false">
<li data-featured="${() => false}"> // returns <li>
