title: Why does String([1,2])=="1,2" and not "[1,2]"?
body: <p>What I want to do is change an array, say,</p>
  
  <pre><code>[1,2,[3,4],17.5]
  </code></pre>
  
  <p>into a sting like</p>
  
  <pre><code>"[1,2,[3,4],17.5]"
  </code></pre>
  
  <p>but not like</p>
  
  <pre><code>"1,2,3,4,17.5"
  </code></pre>
  
  <p>i.e. keeping all of the brackets. I tried using the built in String() function, but that gave me "1,2,3,4,17.5" Is there a built-in function or a code snippet that I can use to get "[1,2,[3,4],17.5]"?<br>
  Thanks!</p>
