How to know the number of key/value pairs in a JSON response?

I have this lines at my ajax request:

      success: function (response) {
        var result = $.parseJSON(response);

Since the response is an array of key/value pairs, how to know the number of pairs?

If it's an Array like Object you can use the following:

console.log(Object.keys(result).length)

If it's just an Array you can use:

console.log(result.length);

Try this way because .length only works with array not with object. so 

var count = 0;
for(var key in json)
    if(json.hasOwnProperty(key))
        count++;
alert(count);

N.B: if it is an array then go with .length alert(result.length);

You have to use length for that:

console.log(result.length);
