How to curry a function across an unknown number of parameters

Question

Say I have a function called multiplyDivide

If I were to call multiplyDivide(2)(3)(4)(6) it would be equivalent to 2 * 3 / 4 * 6

Answer 1

function addValues(a, b) {
   if(b!=undefined)
    return a + b;

   return function(b) {
       return a + b;
   }
}
let output1 = addValues(2)(4);  // 6
let output2 = addValues(2,1);   // 3
console.log(output1);
console.log(output2)
