passing functions into angular instead of 'function()'

I've been working with angular a lot lately and one thing I wanted to do was use a declared function instead of a place that takes the word "function() {}", like in a promise callback for example. I had a few server requests that, on error, all do the same thing, so instead of saying:

.then(function(data) {

}, function(error) {

});

I wanted to do the following:

.then(function(data) {
}, handleError(error));

function handleError(error) { console.log(error); }

but it wasnt working. Did I make a mistake in how I tried to do this or is this just not possible?

When writing handleError(error), you're calling the function (with some error variable as the argument, which probably doesn't even exist). You just want to pass the function:

.then(function(data) {
     …
}, handleError);

No parenthesis!
