Ways to convert a specified number to an array of digits

Method: 1. Using toString() and for loop

const numberToArray = (number) =>  {
    let str = number.toString();
    let result = [];
    for (let i = 0; i < str.length; i++) {
        result.push(Number(str[i]));
    }
    return result;
}
console.log(numberToArray(12345)); // Output:  [1, 2, 3, 4, 5]

Method: 2.Using toString(), split(), and map()

const numberToArray = (number) =>  {
     return number.toString().split('').map(Number);
}
console.log(numberToArray(123456)); // Output:  [1, 2, 3, 4, 5, 6]

Method: 3. Using Math.floor() and a while loop

const numberToArray = (number) =>  {
let result = [];
    while (number > 0) {
        result.unshift(number % 10);  // Get the last digit
        number = Math.floor(number / 10);  // Remove the last digit
    }
    return result;
}
console.log(numberToArray(123456));  // Output:  [1, 2, 3, 4, 5, 6]

Method: 4. Using Array.from()

const numberToArray = (number) =>  {
  return Array.from(number.toString(), Number);
}
console.log(numberToArray(123456)); // Output:  [1, 2, 3, 4, 5, 6]

Method: 5. Using reduce()

const numberToArray = (number) =>  {
   return number
        .toString()
        .split('')
        .reduce((acc, digit) => {
            acc.push(Number(digit));
            return acc;
        }, []);
}
console.log("Number to array: ", numberToArray(123456));
// Output: Number to array: [1, 2, 3, 4, 5, 6]

Method: 6. Using Recursion

function numberToArray(number) {
    if (number === 0) return [];
    return [...numberToArray(Math.floor(number / 10)), number % 10];
}
let result = numberToArray(123456)
 console.log("Result: ", result); // Output: Result:  [ 1, 2, 3, 4, 5, 6 ]
