title: Targeting ES5 with TypeScript in IntelliJ IDEA 14
body: <p>I want to use getters and setters in Typescript. At the moment when I try this I get the following:</p>
  
  <pre><code>error TS1056: Accessors are only available when targeting ECMAScript 5 and higher.
  </code></pre>
  
  <p>How do I configure my compiler in IntelliJ 14? 
  Are there any disadvantages to this? DOes this produce a different type of Javascript that will only work on certain browsers?</p>
  
  <p>Thanks</p>
