Palindrome Integers JS

function palindromeIntegers(arr) {
    for (let i = 0; i < arr.length; i++) {
        let currentNum = arr[i];

        let currentNumAsString = currentNum.toString();
        let currentStringLength = currentNumAsString.length;
        let fromLeft = '';
        let fromRight = '';
        for (let j = 0; j < currentStringLength; j++) {
            let symbolFromLeft = currentNumAsString[j];
            fromLeft += symbolFromLeft;
        }
        for (let k = currentStringLength - 1; k >= 0; k--) {
            let symbolFromRight = currentNumAsString[k];
            fromRight += symbolFromRight;
        }
        if (fromLeft === fromRight) {
            console.log('true');
        } else {
            console.log('false');
        }
    }
}

OR

function palindromeIntegers(array) {
    let arrayLength = array.length;
    for (let i = 0; i < arrayLength; i++) {
        let singleArray = array[i].toString();
        let reversedArray = singleArray.split('').reverse().join('');

        if (singleArray === reversedArray) {
            console.log(true);
        } else {
            console.log(false);
        }
    }
}
