区分控制台和浏览器的javascript

Question

Is there a way to distinguish javascript code that belongs to a website and javascript code that is run from the Console tab in Chrome DevTools?

What I'm trying to do is the following:

Initialize a DEBUG variable to true when I copy paste my javascript code to the Console and false when the javascript code is either located in a <script> tag inside the html file or downloaded from the browser as in an external .js file.

Answer 1

The console has a few global functions. You can do:

var DEBUG = typeof clear === 'function'; // clear() is a global in the console to clear the screen

Just make sure you don't define a global variable clear .
