concat just one element of 2d array in javascript
<p>I am new in javascript so this question might be very basic..</p>

<p>I have a list like this:</p>

<pre><code>[ ["word",number],["word2",number2]......]
</code></pre>

<p>I want to get one string like</p>

<pre><code>concat_str = "word\nword1\n....."
</code></pre>

<p>I see that for 1d array there is this join..</p>

<pre><code>  array.join()
</code></pre>

<p>method..</p>

<p>But how do i do this for just one element of 2d array.</p>
