When you want to pass an object to a web component without going through JSON or some other stringification procedure.

How do you read it in the web component afterwards? Passing it via property sounds quite useful.

Web components are implemented using custom elements which are just plain JS classes that extend the HTMLElement class, so you would access the property the same way you would access a property in a normal JS class.

Event listeners? Image data?

element.srcObject is very useful for <video> elements when the srcObject is a direct stream feed from the camera. I don’t even know how I would go about passing that as a string attribute.
