Do "js exec" blocks still exist?

[wlach]

The documentation mention js exec blocks:

Obviously you have access to values defined in YAML (namespaced under `metadata`) and anything defined in an fenced `js exec` block can be referenced directly.

However, these don't seem to work in the repl and I can't find any references to them in the source. Am I correct in thinking this was an old feature that was taken out?

No, they were used in an older version when it wasn't possible to use all svelte syntax. js exec blocks just used to compile down to script elements which you can now use directly.

I'll update that documentation, must have slipped through when things changed.
