Create a function, add_arrays(), that does the following:

Input: 2 arrays of equal size

• first_array, an array of numbers
• needle array, an array of numbers

Output:

• output array, which has all values from the first array added to the values from the second array

Example:

var first_array = [3,-5,15,4]; var second_array = [3,18,-5,-4]

output = add_arrays(first_array,second_array); console.log(output); //outputs [6,13,10,0];
