debugger; the command i keep forgetting !

So i'm trying to debug ajax responses in a webpage so i go to my chrome browser dev tools, check the src code and nothing....

I keep forgetting to add :

debugger; 

to the ajax response, if we do this, then chrome swings into action and we get our breakpoint so we can debug the response. Hepefully this will help anyone reading this in the future if they are as absent minded as myself.
