What's the best way to update the value of an object within an array

I have an array with objects, each object has a title and a selected state that is a boolean. I want to change only the "selected" value of one of the objects with an action, what would be the best way to do it?

@Victor Giron This is the only way that I've figured out how to do it. Hoping someone else has a better way? https://share.zight.com/yAuBPv8B

You can even consolidate it into just the one formula! Great explainer video 🙏

@Lucas G I'm sure that's easier... how would you use map?

The best is to use the Set formula, link to the array and in the Path point to an array, create two elements for the array, one for the index of the item you want to change and the select element enter "selected".

@ Do you mean like this? Doing it in 1 action instead of 2 like I did?

Okay, so I just did it in 2 steps instead of 1... this is more concise though.

No actually you don't need the other Set (the left-most one)
Point the Path of the right-most Set to the array of index and then selected and the value is the new value

I didn't know that path could take an array containing the index as 1 item and the property you want to modify as another...

Yep that's it. Yeah you can go as deep as you need using an array as the path, same with Get to get a nested value from an array and/or object.
