I'm new to coding and now I want to get the sum of two arrays...
	actually the sum of all their elements. I'll appreciate for your help.

	P.S. Each array includes only integer numbers. Output is a number too.
				

	No examples		
				

Solution by -

	function arrayPlusArray(arr1, arr2) {
		return arr1.reduce((a,b) => a +b, 0) + arr2.reduce((a,b) => a +b, 0); //something went wrong
		}
