title: Converting a string into an array in Typescript?
body: <p>I'm using Angular 4 and a Spring service that I throws an exception with the message being the toString of a List of messages. The problem is that when I receive the exception response and extract the message, instead of being treated like an Array of strings, it's treated as a single string in the format of: <code>"[message 1, message 2]"</code></p>
  
  <p>Is there a way in typescript to easily convert this String into an array of strings? I tried instantiating a new Array with the string like: <code>new Array(errorResponse.error.message);</code> but that didn't really work. </p>
