This simple line of code should work on various browsers. Insert it into your code wherever you need to pause the execution for debugging purposes.
For Windows users: Press CTRL-SHIFT-J OR F12
Mac users can use: ⌥-⌘-J
You can also access it through the wrench menu (Tools > JavaScript Console):
For Windows and Linux users:
Ctrl + Shift + I combination can be used to open Developer Tools.

Open the Chrome browser and press F12 to access the JavaScript debugger, then navigate to the "Scripts" tab.
Select the top JavaScript file and set a breakpoint in the debugger to pause the execution of the code.
Press Ctrl + Shift + J to access Developer Tools.
If you're using Chrome 8.0.552 on a Mac, you'll discover this feature in the menu by navigating to View/Developer/JavaScript Console ... Alternatively, you can simply press Alt+CMD+J.

A brand new feature has been introduced by Google Chrome. This feature allows you to edit your code directly in the browser. The changes made are permanent and reflect on the actual code location.
To access this feature, simply press F12, go to the Source tab (on the right side), navigate to File System, select your code location, and grant permission when prompted by the browser. Your code will then appear highlighted in green, indicating that it can be edited. Any modifications made will be saved permanently.

If you're using a Mac, simply navigate to Google Chrome and click on the menu option labeled View, then select Developer, followed by JavaScript Console.
My go-to method for accessing the javascript debugger is to simply enter this command:
chrome://inspect
F12 activates the developer panel.
CTRL + SHIFT + C opens the hover-to-inspect tool, highlighting elements as you hover and allowing you to click to view them in the elements tab.
CTRL + SHIFT + I Launches the developer panel with console tab.
RIGHT-CLICK > Inspect By right-clicking on any element and selecting "inspect," you can choose it in the Elements tab of the Developer panel.
ESC When viewing the DOM in the "Elements" tab after right-clicking and inspecting an element, you can press ESC to toggle the console up and down, providing a convenient way to utilize both features simultaneously.
To display data on the Chrome console, simply use
console.log(data_to_be_displayed)
