webc:type="js" throws on missing props

[oliverjam]

The webc:type="js" examples in the docs don't work correctly atm, as the "js" type behaves differently to the old "render" type. If a prop is not passed to the component it throws when you try to access it. This means you can't even check if the prop exists 😅

<script webc:type="js">
  if (alt) {
    `<img src="${src}" alt="${alt}">`;
  } else {
    `<a href="${src}">Your image didn’t have an alt so you get this link instead.</a>`;
  }
</script>

[11ty] ReferenceError: alt is not defined
[11ty]     at evalmachine.<anonymous>:2:3
[11ty]     at Script.runInContext (node:vm:141:12)

Doing the equivalent with this.alt in a webc:type="render" component works fine.
