Rails supports transforming aria hashes into dasherized attributes

TIL that aria- attributes get the same treatment in Rails tag helpers as data-. That is, you can do:

• link_to "X", y_path, aria: { pressed: true } -> aria-pressed="true" OR
• link_to "X", y_path, "aria-pressed" => true -> aria-pressed="true"

I can’t find any multi-dash aria properties on MDN, but I imagine Rails will follow the same formatting rules of turning underscores to dashes, e.g.

• link_to "X", y_path, aria: { active_status: "madeup" } -> aria-active-status="madeup"

This is a handy thing to know, since this lets long tag definitions be nicely wrapped and indented across multiple lines, as well as naturally grouping related attributes.
