title: Angular2 multiple constructor implementations are not allowed TS2392
body: <p>How can I get around using multiple constructors within a component? Currently I am getting the error:</p>
  <blockquote>
  <p>'Multiple constructor implementations are not allowed'.</p>
  </blockquote>
  <pre><code>questions: any[];
  constructor( service: QuestionSignupStepOneService ) { 
      this.questions = service.getQuestions(); 
  }
  constructor( service: QuestionSignupStepOneAService ) { 
      this.questions = service.getQuestions(); 
  }
  </code></pre>
  <p>Is there anyway to simplify what I am trying to do? The code compiles properly but will only run through the first service, ignoring the second.</p>
  <p>Edit in 2021: I realized long ago that this was a silly question, but I'm leaving this up because if I did not understand constructors enough so to ask the question then other might find themselves here as well</p>
