Palindrome Java program

function checkPalindrome(string) {

    // find the length of a string

    const len = string.length;

    // loop through half of the string

    for (let i = 0; i < len / 2; i++) {

        // check if first and last string are same

        if (string[i] !== string[len - 1 - i]) {

            return 'It is not a palindrome';

        }

    }

    return 'It is a palindrome';

}

// take input

const string = prompt('Enter a string: ');

// call the function

const value = checkPalindrome(string);

console.log(value);
