JavaScript Number Split into Individual Digits

JavaScript Number Split into individual digits

var number = 12354987,
    output = [],
    sNumber = number.toString();

for (var i = 0, len = sNumber.length; i < len; i += 1) {
    output.push(+sNumber.charAt(i));
}

console.log(output);

/* Outputs:
 *
 * [1, 2, 3, 5, 4, 9, 8, 7]
 */

UPDATE: Calculating a sum

for (var i = 0, sum = 0; i < output.length; sum += output[i++]);
console.log(sum);

/*
 * Outputs: 39
 */

How do I separate an integer into separate digits in an array in JavaScript?

Why not just do this?

var n =  123456789;
var digits = (""+n).split("");

How to split a number into its digits in Javascript?

var num = 4563;var sum = 0;while(num > 0) {  sum += num % 10;  num = Math.floor(num / 10);}console.log(sum);

How can I split array of Numbers to individual digits in JavaScript?

You could join the items, split and map numbers.

var array = [ 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106],    pieces = array.join('').split('').map(Number);    console.log(pieces);

How to split numbers in an array into single digits

You could join and get a new array.

const
    values = [1, 23, 456, 7890],
    result = Array.from(values.join(''), Number);

console.log(result);

Split a number to individual digits in javascript using basic methods

Your error is here:

for (var count = 0; count < number.toString().length; count++)
  arr[count] = number % 10;
number = Math.floor(number / 10);

Only the first statement is included in the for loop, the second only runs after the for loop ends. You need braces around both statements so both run on each iteration.

for (var count = 0; count < number.toString().length; count++) {
  arr[count] = number % 10;
  number = Math.floor(number / 10);
}

But you'll still get the wrong result because you reset the limit for count on each iteration. Set it once at the start.

var count = 0;var arr = [];
function Split(number) {  if (Math.floor(number / 10) > 0) {    for (var count = 0, countLen = number.toString().length; count < countLen; count++) {      arr[count] = number % 10;      number = Math.floor(number / 10);    }  }  return arr;}document.write(Split(2345));
