Digitize number
Converts a number to an array of digits, removing its sign if necessary.
- Use
Math.abs()to strip the number's sign. - Convert the number to a string, using the spread operator (
...) to build an array. - Use
Array.prototype.map()andparseInt()to transform each value to an integer.
const digitize = n => [...`${Math.abs(n)}`].map(i => parseInt(i)); digitize(123); // [1, 2, 3] digitize(-123); // [1, 2, 3]
