js中序列化和反序列化对象的方法是什么？

var a = {
"title": 'good', "name": "ddd", "age": 16
};
//序列化对象
console.log(JSON.stringify(a));
//反序列化对象
var newa = JSON.parse(JSON.stringify(a));

console.log(newa);

<script>
    function serialize(obj, name) {
        var result = "";
        function serializeInternal(o, path) {
            for (p in o) {
                var value = o[p];
                if (typeof value != "object") {
                    if (typeof value == "string") {
                        result += "\n" + path + "[" + (isNaN(p)?"\""+p+"\"": p) + "] = " + "\"" + value.replace(/\"/g, "\\\"") + "\""+";";
                    } else {
