How do you launch the JavaScript debugger in Google Chrome?

Question

When using Google Chrome, I want to debug some JavaScript code. How can I do that?

Answer 1

To open the dedicated ‘Console’ panel, either:

• Use the keyboard shortcuts
  • On Windows and Linux: Ctrl + Shift + J
  • On Mac: Cmd + Option + J
• Select the Chrome Menu icon, menu -> More Tools -> JavaScript Console. Or if the Chrome Developer Tools are already open, press the ‘Console’ tab.
