Im trying to add up all the numbers in each array and print out the total sum of that array. im not sure how to get this code done.

example:

var myArray = [123, 456, 789]

I want the program to print out 6,15,24.

since 1+2+3 = 6 , 4+5+6=15 and 7+8+9= 24.

how would i go about adding each individual number in that array?
