Just so?

You can write applications full of callbacks using libraries like
Twisted or even asyncio and you can build entire applications involving
ajax and such without callbacks as JS got async/await too in ES8 

event handlers are written more or less the same in Pyhton or

yes, i agree that the difference between lambda an anonymous function is
very significant on the way you may think to write your code.

I don't think you mean this is real JS application code :-)

or just

   jQuery(lambda: jQuery("spam").click(lambda: alert("spam clicked")))
