title: What's the difference from installing type definition files using typings vs npm?
body: <p>I've been using the command line and installing <code>TypeScript</code> type definition files <code>.d.ts</code> using <code>Typings</code> from the command line like the following:</p>
  
  <pre><code>typings install dt~jquery --global --save
  </code></pre>
  
  <p>This works perfectly and if done at the root of my project, it gets installed to the <code>typings/globals</code> directory.</p>
  
  <p>I recently had seen tutorials adding <code>typings</code> installations via the <code>devDependencies</code> section in the <code>package.json</code> file for <code>npm</code> to install like the following:</p>
  
  <pre><code>  "devDependencies": {
      "@types/core-js": "0.9.34"
    }
  </code></pre>
  
  <p>I actually did the above and couldn't even find where the <code>d.ts</code> file was put as I didn't see it anywhere in the <code>node_modules</code> folder.</p>
  
  <p>What is the difference between installing typings from the (2) methods above, and where do the typings files end up if using <code>npm</code> to install and pull down the files? </p>
