Digitize number

OSCC · JavaScript, Math · Oct 18, 2020

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() and parseInt() 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]
