Write a JavaScript function on the following: a.) Create a function that will compute the sum of each individual index value from given arrays. Example: arr1 = [2, 5, 6, 7, 0, 11]; arr2 = [5, 7, 1, 3, 9, 2, 13]; arr3 = [3, 7, 1, 1, 23]; result = [10, 19, 8, 11, 32, 13, 13]; = 1 2 - a b.) Create a function to merge two arrays and removes all duplicates elements. Function displays the new arrays and another array that shows the values that we duplicate
