如何编写一个JS函数来转换带有哈希值字符串和一个单词，并输出由相应的header标记括起来的单词

function convertWithHeader(hashValue, word) {
    // 此处编写代码
}

function convertWithHeader(hashValue, word) {
    var hash = hashValue.length;
    // 此处编写代码
}

function convertWithHeader(hashValue, word) {
    var hash = hashValue.length;
    var header = "<h" + hash + ">" + word + "</h" + hash + ">";
    // 此处编写代码
}

function convertWithHeader(hashValue, word) {
    var hash = hashValue.length;
    var header = "<h" + hash + ">" + word + "</h" + hash + ">";
    return header;
}

function convertWithHeader(hashValue, word) {
    var hash = hashValue.length;
    var header = "<h" + hash + ">" + word + "</h" + hash + ">";
    return header;
}
