How to convert an integer into an array of digits

Question

I want to convert an integer, say 12345, to an array like [1,2,3,4,5].

I have tried the below code, but is there a better way to do this?

Answer 1

The solutions proposed work fine in most cases but not with negative numbers.

There is a solution for such cases.

const intToArray = (int) => {
  return String(int).match(/-?\d/g).map(Number)
}

console.log(intToArray(312)) // [3, 1, 2]
console.log(intToArray(-312)) // [-3, 1, 2]
