delete objects from an array

Hi! Hope someone can help me, been struggling for days. I am trying to make an event that will check if an object already exist within an array based on an item_id, delete it if it exist or append it if it does not. The purpose is to collect all items that are selected in an array that will be sent in the body of an api. I am not sure if this is even the best way to do it or not. Any help or feedback is greatly appreciated! Added a screenshot of my current formula. I am able to append and delete, but the deletion is super random and not the element I clicked..

Your check shouldn't use map

Map is used to "rewrite" the array or map items according to the formula

Hi Lucas, thank you for the reply! I see, then I will remove the map, so how should I do the check? It doesn’t work with only include

I mostly use the Filter formula to remove items from an array. Any falsy return value removes the item from the array.

Hi Jacob! I see, thanks for the tip. I tried using Filter, but couldn’t wrap my head around it. I just managed to do it now, don’t know if it’s the correct way, but it works. I am using Find.. 🤷🏻‍♂️

Find only returns a single value. Filter works by running a formula on each item in the array. You could then do a comparison or other calculation on each given item. Only truthy values will be on the output array.

There should bebe some videos on the filter formula.
