How do I convert JSON Array to Javascript array?

So I got this JSON Array in a variable named jsonObject:

    jsonObject = {
    "log": [{
        "date": "15/09/2016",
        "time": "15:35:56",
        "temp": "16.0",
        "humidity": "95.0"
    }, {
        "date": "15/09/2016",
        "time": "15:35:59",
        "temp": "30.0",
        "humidity": "61.0"
    }, {
        "date": "15/09/2016",
        "time": "15:36:03",
        "temp": "30.0",
        "humidity": "60.0"
    }]
}

My goal is to iterate over it and place the data in a table and to do this I want the JSON Array as a normal array in Javascript. I have found many code examples on this, but none of them take into account the name of the array in this case "log". Anyone know how I can get rid of the name and just get an array? I could make the JSON array itne a string, substring it and then convert it into a JSON Array again and then convert it to a Array, but it feels very ineffeficent. Perhaps there is a way to create a 2D array of the JSON Array as a string but I don't know how.

If you want to iterate over the array, try something like this:

var jsonObj = {
        "log": [{
            "date": "15/09/2016",
            "time": "15:35:56",
            "temp": "16.0",
            "humidity": "95.0"
        }, {
            "date": "15/09/2016",
            "time": "15:35:59",
            "temp": "30.0",
            "humidity": "61.0"
        }, {
            "date": "15/09/2016",
            "time": "15:36:03",
            "temp": "30.0",
            "humidity": "60.0"
        }]
    };


 var jsonArr = jsonObj['log'];

 for(var i in jsonArr){
      console.log(JSON.stringify(jsonArr[i]));
 }

JSON objects are javascript variables. If you want log, just grab log.

jsonObject = {
    "log": [{
        "date": "15/09/2016",
        "time": "15:35:56",
        "temp": "16.0",
        "humidity": "95.0"
    }, {
        "date": "15/09/2016",
        "time": "15:35:59",
        "temp": "30.0",
        "humidity": "61.0"
    }, {
        "date": "15/09/2016",
        "time": "15:36:03",
        "temp": "30.0",
        "humidity": "60.0"
    }]
}
logArray = jsonObject.log
