Palindrome Number

Given an integer x, return true if x is a palindrome, and false otherwise.

Solution, Typescript

function isPalindrome(x: number): boolean {
    if(x < 0) {
        return false;
    }

    let remainder = x;
    let placeValue = 1;
    let val = 0;
    while(remainder > 0) {
        let digit = remainder % 10;
        val = val * 10 + digit;

        if(val > x) {
            return false;
        }
        remainder = Math.trunc(remainder / 10);
    }

    return val === x;
};

I totally one shot submitted this and was surprised it worked. 😈🤠
