I’d like to create a scheduler app that contains a list of events. Each event has a startDate and an endDate . I’d like to determine which events overlap so I can place events in a different column. Is there a way to apply some sort of groupBy function to accomplish a way for me to group them?

if your events are sorted by start date, you can fold into a list of lists, appending the event to the current list while the event's start date is less than the latest endDate of the current list
