## The prompt:

Given a number, write a function that can determine if the specified number is a palindrome. For example 134 is not a palindrome because reversing it results in 431. A palindrome would return the same value, for example 313 is a palindrome because reversing it results in the same number, 313 again.

Solution

/**
* @param {number} x
* @return {boolean}
*/
var isPalindrome = function(x) {
if(x<0) {
return false
}
let str = "" + x
let rs = str.split("").reverse().join("")
if(rs !== str) {
return false
}
return true
};
// Some test cases
`
False Expected: ${isPalindrome(123)}
True Expected: ${isPalindrome(3443)}
False Expected: ${isPalindrome(6215)}
True Expected: ${isPalindrome(18781)}
False Expected: ${isPalindrome(-51)}
