if ( condition ) {
callback(data)
}
callback(error)

--is a lot different than--

if ( condition ) {
callback(data)
} else {
callback(error)
}

callbacks are not return statements 🀦‍♂️

    I'm sick of seeing this.

    I mostly work with PL/SQL, and I cant count the times I see something like that.

    Or ifs checking if a error message is returned, but you have a exception catching that and exiting the function

    What if the success statement throws a success exception?

    @alexbrooklyn that would’ve saved me two hours of debugging. I’m okay with that today.

    Callback && callback(data || error);

    How about that?
    Or use promises? :p

    @bashleigh I'm stuck passing this callback function to a 3rd party library. I'm getting ready to just copy and paste the parts of the library I need into our own codebase and refactor it the right way.
