Get the largest value from the array in JS or jQuery
<p>Using flow chart lib I’m plotting a graph. Below is the <code>x</code> and <code>y</code> coordinates of the graph as an array.</p>

<pre><code>var plottingPoints  = [[0, 3], [4, 8], [8, 5], [9, 23], [10, 2]];
</code></pre>

<p>I just need to pick largest value of the <code>y</code> coordinate (ie 23). Please need support of expertise. </p>
