Determine whether the palindrome

// determines whether palindrome: if n = 1234321, then n is a palindrome

let readline = require("readline-sync");

let newNum = 0;

console.log ( "Please enter the number you want to judge a palindrome");

let oldNum = parseInt(readline.question(""));

// First assign oldNum to the temporary variable temp, it has been within temporary variables to be changed

// key is taken every digital temp = temp / 10 for obtaining the foregoing

for (let temp = oldNum; temp != 0; temp = parseInt(temp / 10)) {

// remove every last one pair can take more than 10

// After every ride out the next 10 to form a new number

newNum = newNum * 10 + temp % 10;

}

newNum === oldNum console.log ( 'is a palindrome'):? console.log ( 'is not a palindrome number');
