title: Chrome DevTools do not show .js files
body: <p>I'm developing a small Angular app and I'm trying to debug it in Chrome DevTools. However, I can only see .ts files there.</p>
  
  <p>How can I see and debug the .js files that .ts files compile to?</p>
  
  <p>My 'Enable JavaScript source map' option in DevTools settings is turned on.</p>
