How to do Array to array multiplication in Javascript?

Question

Example:
[2,3,5] × [4,6,8]
Answer = [8,18,40]

Answer 1

const matmul = (arr1, arr2) =>
arr1.map((x, i) => x * arr2[i]);

Answer 2

We can accept the array to be a matrix then we can use matrix multiplication.
But we must remember that in matrices,
A × B ≠ B × A always

And how do we apply this matrix multiplication? .
I haven't come across it yet on my JavaScript tutorial.

Can you give a code example in Javascript please.
