      The goal of this quickstart is to write a component in TypeScript that prints a string.
      To get started, clone the TypeScript quickstart repository:
  
    pre.prettyprint
      $ git clone https://github.com/angular/ts-quickstart.git
      $ cd ts-quickstart
  
    p.
      For the sake of this quickstart we recommend using the
      <a href="https://github.com/angular/ts-quickstart"> <code>quickstart</code> GitHub repository</a>.
      This repository provides a faster start than building from <code>npm</code>.
      This repository includes the Angular distribution and type definitions for TypeScript.
      
    p.
      Create two files, <code>index.html</code> and
      <code>app.ts</code>, both at the root of the project:
  
    pre.prettyprint
        $ touch app.ts index.html
