Json string results number counting with JavaScript

Question

I got 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
        }]
    }
}

How do I get the number of groups (not sure of the proper term) under ResultSet.Results using JavaScript?

For instance, in the above example, it is 2, ie. ResultSet.Results[0] & ResultSet.Results[1]

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

Correct terminology would be the number of objects in the Results array. Since it's an array, ResultSet.Results.length works perfectly as mentioned below. — Vigrond

ResultSet.Results.length

This should work, as it is a normal array.
