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

First, the integer is converted string & then to array. Using map function, individual strings are converted to numbers with the help of parseInt function. Finally, that array is returned as the result.

const digitize = n => [...`${n}`].map(i => parseInt(i));
