Hey Clifford

Thanks for posting in the Lucid Community 🥳. The Javascript Console helps debug JavaScript codes based on the browser environment or server-side environment. It basically helps us help you .

You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac). It can be closed either by clicking the "X" in the top-right corner of the console or by repeating the same shortcut. 

Hope this helps explain--let us know if you have any other questions!

If anyone else out there is experiencing issues don't hesitate to reach out to us directly at support@lucidchart.com. We would be happy to help!
