How to reverse a number in TypeScript

Answer 1

function reverseNumber(n: number) : number{
    let reverse: number = 0;
    
    while (n != 0) {
        let reminder = n % 10;
        reverse = reverse * 10 + reminder;
        n = Math.trunc(n / 10);  
    }
    return reverse;
}
    
const n: number = 90812;
const reverse_n: number = reverseNumber(n);
    
console.log(reverseNumber(n));
