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

I'd go with

var arr = n.toString(10).replace(/\D/g, '0').split('').map(Number);

You can omit the replace if you are sure that n has no decimals.
