// Function to reverse a number, handling negative numbers as well.
function reverseNumber(number) {
  let reversedNumber = 0;
  let isNegative = false;
  
  // Check if the input number is negative.
  if (number < 0) {
    isNegative = true;
    number = Math.abs(number); // Convert negative number to positive for reversal.
  }
  
  // Reverse the positive number.
  while (number !== 0) {
    reversedNumber = reversedNumber * 10 + (number % 10);
    number = Math.floor(number / 10);
  }
  
  // If the input was negative, make the result negative as well.
  if (isNegative) {
    reversedNumber *= -1;
  }
  
  return reversedNumber;
}

// Testing the reverseNumber function.
console.log(reverseNumber(-2345)); // Output: -5432
console.log(reverseNumber(12345)); // Output: 54321

// Another method to reverse a number using string manipulation.
function reverseNum(n) {
  let reversedString = n.toString().split('').reverse().join('');
  return Math.sign(n) * parseInt(reversedString);
}

// Testing the reverseNum function.
console.log(reverseNum(12345)); // Output: 54321
console.log(reverseNum(-345));  // Output: -543
