title: Default Angular-CLI Project Fails in Safari - culprit strict mode?
body: <p>I have installed the most-recent version of the angular-cli and created a brand new project (ng new my-app). This creates the always-stylish "Welcome to App" with the Angular logo and links to Tour of Heroes, the CLI Documentation, and the Angular blog. I can ng serve this and access it locally on my Windows machine using Chrome and Firefox.</p>
  
  <p>Where this gets strange is when I try to access the same locally hosted app through Browserstack. When I hit it from a Mac running Safari 11, all works as expected. </p>
  
  <p>However, when I try to access via a Mac device (iPad for example) running Safari 10+, the app will not load and I get the error message: "SyntaxError: Unexpected keyword 'const'. Const declarations are not supported in strict mode". The error message is tied to a location in my vendor.bundle.js (in an eval).</p>
  
  <p>From my reading, it appears that older versions of Safari don't play nice with consts when strict mode is enabled. But, I am hoping there is a work-around.</p>
  
  <p>How are others handling this? I am not an angular-cli expert, so if there is an obvious solution, my apologies for not seeing it.</p>
  
  <p>Any assistance would be greatly appreciated.</p>
