How to find the union of two Int16Arrays in JavaScript

Question

I have two Int16Arrays:

const a = new Int16Array([ 0, 0, 0, 1 ])
const b = new Int16Array([ 1, 0, 0, 0 ])

I need to find a way to unify these two arrays, so that I receive an output like so:

Int16Array(4) [ 1, 0, 0, 1 ]

the length of the two arrays will always be the same, and all indexes will be either 0 or 1 for both arrays. Thank you for any help you can offer!

Answer 1

const a = new Int16Array([ 0, 0, 1, 1 ])
const b = new Int16Array([ 1, 0, 1, 0 ])

const result = new Int16Array(a.map((e, i) => e | b[i]))

console.log(result)
