how to translate this JS code into HS?

[warcayac]

document.body.addEventListener("authOk", function(evt){
  console.log(evt.detail.value);  // it displays: 12345
})

I tried with:

_="on authOk js(evt) console.log(evt.detail.value) end"

but it displays error messages only like this:

Cannot read properties of undefined (reading 'detail')

[jeanfortheweb]

on authOk log event.detail.value

i guess. untested

see https://hyperscript.org/docs/#event_destructuring

_="on authOk(value) log value end"
