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.

[throwitaway1123]

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.

Thanks understood, that makes it quite simple and intuitive thinking about it.

The author of the thread is arguing against properties.

[throwitaway1123]

Yes, I know. I wasn't making a prescriptive comment about whether or not developers should use properties, I was just making a descriptive comment about how properties are accessed in a web component to answer the specific question politelemon asked.

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.
