Counting numbers and displaying results using JavaScript with a JSON string

Looking at this JSON string

{
    "ResultSet": {
        "version": "1.0",
        "Error": 0,
        "ErrorMessage": "No error",
        "Locale": "us_US",
        "Quality": 40,
        "Found": 2,
        "Results": [{
            "quality": 72,
            "latitude": "19.113130",
            "longitude": "72.873140",
            "woetype": 22
        }, {
            "quality": 72,
            "latitude": "19.094630",
            "longitude": "72.847460",
            "woetype": 22
        }]
    }
}

In JavaScript, how can I determine the number of elements under ResultSet.Results?

For example, in the JSON provided above, it would be 2, corresponding to ResultSet.Results[0] and ResultSet.Results[1]

"Results": [{
            "quality": 72,
            "latitude": "19.113130",
            "longitude": "72.873140",
            "woetype": 22
        }, {
            "quality": 72,
            "latitude": "19.094630",
            "longitude": "72.847460",
            "woetype": 22
        }]
