Answer 1

Using JavaScript reverse() and Math.sign() you can reverse a number both positive and negative numbers.

var enteredNum = prompt("Enter integer");

function reverseInteger(enteredNum) {
    const reveredNumber = enteredNum.toString().split('').reverse().join('');
    return parseInt(reveredNumber)*Math.sign(enteredNum);
}

alert(reverseInteger(enteredNum));
