I’m trying to figure out how to pass arrays and objects data back and forth to controller values.
Suppose I have a controller:
<div data-controller="archive" data-archive-terms-value=""></div>
And some button somewhere like:
<button data-archive-target="filterButton" data-value="(an array or object here)" data-action="click->archive#updateTerms"></button>
In the updateTerms function, how do I pass an array back to data-archive-terms-value? I can pass a string or a number back, but I don’t know how to properly “prepare” the array or object data so that the data value attribute on the controller is updated. It always resolves to  when I set this.termsValue to the new array or object.
