JavaScript: a simple solution to check if a number is palindrome

In this article we will look at the simplest solution to check if a number is palindrome in JavaScript.

We essentially need to transform the number into a string and compare that string to its reversed version. If the two strings are equal, the number is palindrome.

'use strict';

const isPalindrome = (num = 1) => {
    const str = '' + num;
    const rev = str.split('').reverse().join('');
    return str === rev;
};
