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

You can do it using some functional style:

const a = [1,2,3]
const b = [4,5,6]

const f= a.concat(b).map((v,i,arr)=>{
  if ( i!isNaN(n))

console.log(f)
