2d javascript array using json notation (help me clear up the confusion)
<p>I am writing Tetris in JavaScript as practice, and i am somewhat confused by the array notation that i am using. 
Here's the array that i have that stores all my pieces. </p>

<pre><code>var pieces = [[[1,1],
               [1,1]],

              [[1,0],
               [1,0],
               [1,1]],

              [[0,1],
               [0,1],
               [1,1]],


              [[0,1,0],
               [1,1,1]],

              [[1,0],
               [1,1],
               [0,1]],

              [[0,1],
               [1,1],
               [1,0]]];
</code></pre>

<p>What is this notation called? How is this difference from just saying "new array()"?</p>

<p>Thank you!</p>
