When I open the console on some sites like Facebook and Blockchain, I get a warning like the one below, I was wondering how I can do that on my site? Display a warning telling the user it's dangerous and he should not paste anything there.
How can I display a warning to users who open the Chrome console, like Facebook and Blockchain does?

                    It is just a console.log – epascarello Feb 10 '17 at 17:25

                    They're just logging to the console, and they make sure not to have anything else in the log, just that message – chiliNUT Feb 10 '17 at 17:26

            You can style console.log messages:
console.log('%cStop!', 'color: red; font-size: 30px; font-weight: bold;');
