Javascript get value from array

Question

If I have the following code in Javascript:

var line0 = [["2012-07-01",1.8182],["2012-08-01",1.4000],["2012-09-01",1.7500]];

How can I obtain the first date, which in this case is: "2012-07-01"

Thanks in advance.

It's the 0-th element of the array that is the 0-th element of line0, so:

line0[0][0]

You can do it like that:

<script type="text/javascript">
var line0 = [["2012-07-01",1.8182],["2012-08-01",1.4000],["2012-09-01",1.7500]];
alert(line0[0][0]);
</script>
