How to get JSON object length in jquery?

Question

i have two JSON objects inside a JSON array as below

array.put(resObj);

array.put(resObjPrd);

i'm returning this array as a Jquery ajax response.Can anyone please explain me how can i get the length of second object using jquery? Here is my Jquery ajax code.

$.ajax({
    type: 'POST',
    url: "fetch",
    dataType: 'json',
    data: {
        clientidedit: clientidedit
    },
    success: function(data) {
        alert(data[1]);

    }
});

Object {} does not have .length property . Though could use JSON.stringify() to get string representation of Object , then return .length of stringified object — guest271314

Could use JSON.stringify() to retrieve string representation of Object , then return .length of stringified object

var obj = {"abc":123};
var objStr = JSON.stringify(obj);
console.log(objStr.length)
