title: A type literal property cannot have an initializer in TypeScript
body: <p>This is my class in title gives me an error of </p>
  
  <blockquote>
    <p>"A type literal property cannot have an initializer"</p>
  </blockquote>
  
  <p>If I remove <code>title</code> its working fine, I'm using <code>Angular 4.3.1</code></p>
  
  <pre><code>export class MyClass{
      data:[
        {
          blood:string;
          title:string = 'Blood Pressure - Systolic (mm/Hg)';
        }
      ]
  }
  </code></pre>
  
  <p>Thanks a lot.</p>
