**const** num1 = parseInt(prompt(‘Enter the first **number** ‘)); **const** num2 = parseInt(prompt(‘Enter the second **number** ‘)); **const** num3 = parseInt(prompt(‘Enter the third **number** ‘) The total of the numbers is then calculated. sum = num1 + num2; **const** sum = num1 + num2; Finally, the total is shown.

To **sum** an **array** in a JavaScript **array**, use the for Loop. Copy const **array** = [1, 2, 3, 4]; let **sum** = 0; for (let I = 0; I **array**. **length**; i++) **sum** += array[i]; for (let I = 0; I **array**. **length**; i++) **sum** += array[i]; for (let I = 0; I **array**. **length**; i++) **sum** += array[i]; for (let I = 0; log(sum); log(sum); log(sum); log(sum); log(sum To save the result, we set the variable **sum** to 0 and use the for loop to visit each element and add them to the array’s total.
