math - JavaScript Number Split into individual digits

Question

I am trying to solve a math problem where I take a number e.g. 45, or 111 and then split the number into separate digits e.g. 4 5 or 1 1 1. I will then save each number to a var to run a method on. Does anyone know how to split a number into individual digitals?

For example I have a loop that runs on an array :

for (var i = 0; i < range.length; i++) {
  var n = range[i];
}

For each number, I would like to split its digits and add them together?

Answer 1

var num = 123456;
var digits = num.toString().split('');
var realDigits = digits.map(Number)
console.log(realDigits);
