Standard way to debug javascript / jquery

Question

This is my usual way to debug javascript. Enable alert (0); to break the stream and find out what is happening.

sometimes when i need some breakpoints i do

alert('the flow is now in function 1');
alert('the flow is now in function 2');

or sometimes just

alert('success');

I would like to know if there is a standard way for debugging accepted as I find my current method very intrusive.

thanks in advance..:)

 JavaScript: warning (. document.getElementById ('comments-2521535') innerHTML);

and press Enter to start the fragment on the page. It is very similar to the Firebug console.
