Debugging

There are a few basic tools and techniques that can help you to debug applications.

Use Chrome DevTools to debug your client-side code.

  • To open DevTools on Windows and Linux, press Control-Shift-I in your Google Chrome browser. On Mac, press Option-Command-I.
  • To quickly find which line of code is failing, enable the Pause on all exceptions option before running your code.

To learn more about debugging JavaScript on Google Chrome, refer to the Google Chrome's DevTools website.
