This is a bit of a weird situation, but say I have the following function:

function myFunction(name, age, job){...}

Is there a way to get keys / loop through the required params for it (not the argument array passed to it), so it would be something like:

for(required_param_keys_by_myFunction){
 console.log(key) // --> name, age, job
}

I saw that question but was hoping for a better way, I mean these must be defined somewhere? – Mankind1023 Sep 14 '17 at 20:34
Hence I did not hammer close your question... – mplungjan Sep 14 '17 at 20:35
Please describe what the real goal is? Why would you want to print the names of those variables? Surely the code should work exactly the same if only the names of variables were changed. You are trying to do otherwise. – trincot Sep 14 '17 at 20:36
there is no new news. – Nina Scholz Sep 14 '17 at 20:36
Actually I'm trying to use that list to dynamically validate functions. – Mankind1023 Sep 14 '17 at 20:37
