Not necessarily. Recall that JavaScript does not care about missing
input parameters for functions, it just treats them as undefined. You
can exploit this to make the new parameter optional. An example would

function myFunction($obj)
    if ($obj == undefined
        || ! $obj instanceof jQuery
        || $obj.length == 0
    ) {
        // input was invalid, so we
        // operate on the whole document
        $obj = $('body');


This will allow you to leave alone all the calls to initTooltips() that
are already in the code base (and that have no arguments). Hope this
makes sense.
