Question

I have code that looks like this:

function getTopicOptions(accountID, showTitles, showSelectGroup) {
    "use strict";

    var accountID = store.getItem('AccountID');  
    showTitles = (showTitles !== 'undefined') ? showTitles : 'Y';
    showSelectGroup = (showSelectGroup !== 'undefined') ? showSelectGroup : 'Y';

The idea is that if showTitle and showSelectGroup are not supplied then they will get the default of “Y”.

Is there a way do this with function overloading or a way to have the function parameters checked (jslint?) or a way to simplify what I need to do without the undefined check?

Answer 1

You could do something like this:

showTitles = showTitles || 'Y';

or this would work as well, but is more verbose

showTitles = showTitles ? showTitles : 'Y';

I’m not sure where function overloading comes into your question.
