How to magically get Object key?

Question

It is possible to get hero key in the translate function?

let books = {
  hero: translate([
    'Batman',
    'Superman',
    'Ironman'
  ])
}

function translate(param1) {
  return ...
}

Maybe there is some magic how to get calling key name ? :) Thanks!

You're asking if a function called as part of a property initializer in an object initializer can access the name of the property its return value will be used to initialize.

No, it can't. Functions have no knowledge of how their return value will be used.
