This must be a very simple thing, but I am well and truly stuck: how to manipulate an observable array in ionic/ Angular/Typescript? The HTTP call gets the array just fine, but I want to filter and display only the five most recent events (against an "eventdate" value in the JSON file).
Again, the entire event list displays fine, but my blindness involves how to display selected subsets from the observable array.
Days of ineffective googling and looking at O'Reilly books have gotten me no closer. Thank you for any tips or tutorials or whatever!
