    Could anyone please tell what i am doing wrong in this code. 3 test cases are failing - 

    function isBalanced(s) {
    // Write your code here
    if(!s || s == "" ) {
        return "NO"
    }
    let arr = s.split("");
    let arrLength = arr.length;
    if((arrLength % 2) != 0) {
        return "NO"
    }
    let bracketsObj = {
        "(": ")",
        "{": "}",
        "[": "]"
    };
    let closingBrackets = Object.values(bracketsObj);
    let tempArray = [];
    for(let i = 0; i< arrLength; i++) {
        let isMatched = false;
        if(closingBrackets.includes(arr[i])) {
            if(bracketsObj[tempArray.pop()] != arr[i]) {
                return "NO";
            }
        } else {
            tempArray.push(arr[i]);
        }
    }
    return "YES"
}
