[Javascript] Anonymous functions in parameter space

[Paul M Foster]

Hopefully, I'll get the terminology right here. If you, please correct
me.

Why is it common practice to write pass anonymouse functions as
parameters to other functions in javascript? Example:

function alfa(function(){ do_some_stuff; }){ do_other_stuff; };

I see this a lot, and it's unbelievably confusing to decode/read. Why is
it done this way? Instead, why not do it this way:

function bravo() { do_some_stuff; };

var charlie = bravo();

function alfa( parm ) { do_other_stuff; };

alfa(bravo);

Any help?

Paul
