title: Typescript Error: TS2339:Property 'map' does not exist on type 'string'
body: <p>It seem typescript doesn't currently have the new object types in ECMAScript 2015 (6th Edition, ECMA-262).  Here is my code:</p>
  
  <pre><code>const SkipAny: string = requestBody.SkipAny;
  CurTester.SkipAny = SkipAny.map((value)=&gt;{return new RegExp(value)});
  </code></pre>
  
  <p>The error I get is:</p>
  
  <pre><code>TS2339:Property 'map' does not exist on type 'string'
  </code></pre>
  
  <p>I would like to find a work around for this but I do want to use map.  Is there anyway to ignore this rule in tslint?</p>
