Question

What’s a good way to learn how to convert javascript to coffeescript?

I’m adding Fullcalendar to my RoR app. The following code is from one of the Fullcalendar demos.

            select: function(start, end, allDay) {
            var title = prompt('Event Title:');
            if (title) {
                calendar.fullCalendar('renderEvent',
                    {
                        title: title,
                        start: start,
                        end: end,
                        allDay: allDay
                    },
                    true // make the event "stick"
                );
            }
            calendar.fullCalendar('unselect');
        },

I need to learn how to turn that code into coffeescript.

Thanks!

The CoffeeScript page has a good comparison.

In rails you can append .coffee to your javascript filename and sprockets will then compile the CoffeeScript into javascript.

It should look something like this:

        select: (start, end, allDay) ->
        title = prompt 'Event Title:'
        if title
            calendar.fullCalendar 'renderEvent',
              title: title,
              start: start,
              end: end,
              allDay: allDay,
            true
        calendar.fullCalendar 'unselect'
