OTHER TIPS
Try adding this to your source:
debugger;
It works in most, if not all browsers. Just place it somewhere in your code, and it will act like a breakpoint.
Windows and Linux:
Ctrl + Shift + I keys to open Developer Tools
Ctrl + Shift + J to open Developer Tools and bring focus to the Console.
Ctrl + Shift + C to toggle Inspect Element mode.
Mac:
⌥ + ⌘ + I keys to open Developer Tools
⌥ + ⌘ + J to open Developer Tools and bring focus to the Console.
⌥ + ⌘ + C to toggle Inspect Element mode.
Press the F12 function key in the Chrome browser to launch the JavaScript debugger and then click "Scripts".
Choose the JavaScript file on top and place the breakpoint to the debugger for the JavaScript code.
Ctrl + Shift + J opens Developer Tools.
In Chrome 8.0.552 on a Mac, you can find this under menu View/Developer/JavaScript Console ... or you can use Alt+CMD+J.
Here, you can find the shortcuts to access the developer tools.
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.

For Mac users, go to Google Chrome --> menu View --> Developer --> JavaScript Console.
Now google chrome has introduce new feature. By Using this feature You can edit you code in chrome browse. (Permanent change on code location)
For that Press F12 --> Source Tab -- (right side) --> File System - in that please select your location of code. and then chrome browser will ask you permission and after that code will be sink with green color. and you can modify your code and it will also reflect on you code location (It means it will Permanent change)

The most efficient way I have found to get to the javascript debugger is by running this:
chrome://inspect
From the console in Chrome, you can do console.log(data_to_be_displayed)
.
