How to use values in parameter of invocation of the function?

Question

I am not sure if the question has the right terms/words but I have the code and should explain the problem.

 function canDrive(age,_yes,_no){ if (age >= 16) { return _yes; } else { return _no; } } function myFunction() { document.getElementById("demo").innerHTML = canDrive(30,"YES WAY","NOWAY"); } myFunction(); 

 <p>Can he drive <span id="demo"></span></p> 

The problem is that invocation where i do not have access is structured like this. It seems to be valid

canDrive(30)("YES WAY","NOWAY");

How can i access YES WAY and NOWAY ? in the above scenario? If I can understand how it works i can solve a big problem. Thank you

Answer 1

var canDrive = function(age) {
   return function(_yes, _no) {
       if  (age >= 16)
           return _yes;
       return _no;
   }
}

Answer 2

Based on my understanding of your question, I assume you are looking for this:

 function canDrive(age) { return function(yes, no) { return age >= 16 ? yes : no; } } console.log(canDrive(30)("YES WAY", "NOWAY")); 

canDrive returns a closure which returns one of the two supplied arguments based on age .
