positive.code:     your code to browser-compliant JavaScript as you work. This quickstart uses the TypeScript
      compiler in <code>--watch</code> mode, but it is also possible to do the translation in the browser as files
      are loaded, or configure your editor or IDE to do it.
    p.
      The repository includes a file <code>tsconfig.json</code>.
      Many tools &mdash; including the TypeScript compiler &mdash;
      know to read this file so we don't need to configure them or add command-line options.
  
    pre.prettyprint
      $ npm install -g typescript@^1.5.0-beta
      $ tsc --watch

      The goal of this quickstart is to write a component in TypeScript that prints a string.
      We assume you have already installed <a href="https://docs.npmjs.com/getting-started/installing-node">Node and npm</a>.
  
    p.
      To get started, create a new empty project directory. All the following commands should be run
      from this directory.
  
    p.
      To get the benefits of TypeScript, we want to have the type definitions available for the compiler and the editor.
      TypeScript type definitions are typically published in a repo called <a href="http://definitelytyped.org/">DefinitelyTyped</a>.
      To fetch one of the type definitions to the local directory, we use the <a href="https://www.npmjs.com/package/tsd">tsd package manager</a>.
  
    pre.prettyprint
      $ npm install -g tsd
      $ tsd query angular2 --action install
  
    p.
      Next, create two empty files, <code>index.html</code> and <code>app.ts</code>, both at the root of the project:
  
    pre.prettyprint
      $ touch app.ts index.html
