javascript - Style console.log output and run functions -


After doing a little bit of scandal around the source code for

, I saw how to console users to communicate with them (Only works in Chrome).

Enter image details here

In addition, if I If I enter joinUs () on the console log, then a function is run that directs me to a new page.

I tried to run my function in the console logs by declaring the function of your website: 

  function testFunc () {console.log ('Hello World!'); }   
 But if I try to enter  testFunc ()  on the console log, I get the following error:  
 < code> ReferenceError: testFunc is not defined   
 Is there any information about styling the output of console logs and how to run a function from the console? For the style, you can check - if you read through the code then I'm sure you can. Understand how it works.  
 Available to be available  testfunc , specify it clearly on  window , do  window.testFunc = function () {console.log ('Hello World!')}; . it should work.
