Infinity Currying

function addition(a) {
  return function (b) {
    if (b) return addition(a + b); //calling the parent function loaded with the current sum of first two params as a second param upon third param
    return a;
  };
}
console.log(addition(4)(2)(3)());  //last paranthesis is empty , because we will fetch the updated sum via "a", since the updated sum will be sent to "a"

if parameters are a group of numbers then :
function add(...args1){
   let sum = args1.reduce((s, a) => s += a, 0)
   return function resultFn(...args2){
       if(arguments.length) {
           sum += args2.reduce((s, a) => s += a, 0);
           return resultFn;
       }
       return sum;
   }
}
