Create a function in JavaScript called "sum" that takes in an array as a parameter and returns the sum of all of the EVEN numbers in a given array. Please note: the array passed in can have any data type, i.e. Strings, Numbers, Booleans, undefined, etc. HINT: the expression typeof will help discern var types. For example if I have: var x = 4, and I do typeof(x) - the output would be "Number" Example run: sum([1, 4, 8, 10,...

1. Given an array of numbers, write a function to return an array of numbers' where productsli] is the Input: [1, 2, 3,4, 5] Output: [(2*3*4*5), (1 3*4*5), (1*2*4*5), (1*2*3*5), (1*2*3*4)1 [120, 60, 40, 30, 24] You should do this in O(N) without using division.
