Javascript - Sum two arrays in single iteration

Question

I want to sum each value of an array of numbers with its corresponding value in a different array of numbers, and I want to do this without looping through each individual v

Answer 1

Another way to do it could be like that

var array1 = [1,2,3,4];
var array2 = [5,6,7,8];

var sum = [...array1].map((e,i)=> e+array2[i]); //[6,8,10,12]

In this case [...array1] is the same to [1,2,3,4]
