Interactive debugger console

The interactive Console pane shows you stack traces and everything that was logged in your code (for example, using console.*).

The Console pane is also a read-eval-print loop(REPL) so you can run JavaScript code snippets in it and interact with the page that you are currently debugging.

Run JavaScript in the Console

Start typing a statement at > in the input field. As you type, PyCharm suggests variants for completion.
Select the relevant statement and press Enter. PyCharm shows its value in the console.

PyCharm shows previews for objects so you do not need to expand them. If you still expand an object, you get an overview of just its own properties, the __proto__ contents are hidden by default.

Navigate to source code

At each line with output of console.*, PyCharm shows the name of the file and the line where it was called. Click this link to jump to the call in the source code.
The Console also shows stack traces. Click the link next to a reported problem to jump to the line of code where this problem occurred.

Filter out messages

The Console tab shows objects in a tree view, with stack traces collapsed by default. Warnings console.warn(), errors console.error(), and info console.info() messages have different icons and background colors to make them easier to notice.

To hide log messages of specific types, click and select the severities to filter out.

Group messages

The log messages grouped using console.group() and console.groupEnd() are displayed as a tree. To show the output collapsed by default, use console.groupCollapsed().

Apply CSS styles

Use CSS and the %c marker to apply styles to log messages.

See Styling console output with CSS for details.
