How do I merge query parameters into URL like Nomad List?

Nomad List is a crowdsourced database of cities for Digital Nomads. They do this really cool thing for SEO where as you apply filters, the database is queried and the home page dynamically updates to display the best matching city. Crucially, the results of each filter query are also unique URLs.

For example, if I want to filter place in europe, it appends this, places-in-the-european-union, instead of ?place=european-union

The HTML markup of their link is interesting. Does anyone have an idea of how to do this?

<div class="filter half choices c1">
            <div class="choice active" data-filter-slug="near-a-beach" data-filter-slug-position="after" data-filter-target="tags" data-filter-type="partial-match" data-filter-value=",beach">
                            <span>⛱ Near beach</span>
            </div>
</div>
