Can I see how long a JavaScript function takes to execute in Firebug?

Question

Is there a way to get a timeline for "normal" JavaScript functions like there is for Ajax, images, etc. in Firebug?

Answer 3

You can add a date object at start and end of the method and do some thing like

This is only for performance checking and later you can remove the start date and end date.
