Array Sum

                
                    function arraySum(arr) {
                        let sum = 0;
                    
                        for (let index = 0; index < arr.length; index++) {
                            const element = arr[index];
                            sum += element; // sum = sum + element;
                        }
                        return sum;
                    }
                    console.log(arraySum([3, 5, 2])); // 10
                    console.log(arraySum([6, 5, 11])); // 22
