Difference of Volumes of Cuboids

In this simple exercise, you will create a program that will take two lists of integers, a and b. Each list will consist of 3 positive integers above 0, representing the dimensions of cuboids a and b. You must find the difference of the cuboids' volumes regardless of which is bigger.

My code:


                        function findDifference(a, b) {
                            let aResult = 1;
                            let bResult = 1;
                            for (let i = 0; i < a.length; i++){
                              aResult *= a[i];
                            }
                            for (let j = 0; j < b.length; j++){
                              bResult *= b[j];
                            }
                            if (aResult > bResult){
                              return aResult-bResult;
                            }else{
                              return bResult-aResult;
                            }
                          }

And that's the best solution among all users:


                        function find_difference(a, b) {
                            return Math.abs(a[0]*a[1]*a[2]-b[0]*b[1]*b[2]);
                          }
