Research direction

Start by reproducing the HTML hyperscript snippet from the issue with the object containing name and age, then inspect how the existing for-loop handles its input. Confirm how object properties should expose key and value, and consider the work complete when the example iterates without the reported TypeError and logs both properties.

Written by the indexing model from the issue text.

Description

I tried something that was not documented: "Iterate over an object"
code:

    <script type="text/hyperscript">
      init
        set $o to { name: "john", age: 30 }
        for value in $o index key
          log key
          log value
        end
      end
    </script>

But I could not get it working. Trying multiple methods, most of them resulted into an error.
console:

Uncaught TypeError: i.iterator is undefined

    n https://unpkg.com/hyperscript.org:1
    w https://unpkg.com/hyperscript.org:1
    promise callback*w https://unpkg.com/hyperscript.org:1
    <anonymous> https://unpkg.com/hyperscript.org:1
    <anonymous> https://unpkg.com/hyperscript.org:1

Since this works in normal javascript I think there must be a way to do this in hyperscript.
Please let me know how to do this.
