Hi! Quick question about array manipulation.I’m building an array of objects { id, commentsCount }, initially empty, that gets updated from a child component event. Each time a user comments, the event returns the post ID.The goal is to keep a temporary local array of posts and their comment counts to update the UI without refreshing or calling the API.How should I handle adding/updating objects in this array with these two cases : If an object with the same id exists → increment commentsCountIf not → add { id, commentsCount: 1 } to the arrayThanks you

Hi! Quick question about array manipulation.

I’m building an array of objects { id, commentsCount }, initially empty, that gets updated from a child component event. Each time a user comments, the event returns the post ID.

The goal is to keep a temporary local array of posts and their comment counts to update the UI without refreshing or calling the API.

How should I handle adding/updating objects in this array with these two cases :

If an object with the same id exists → increment commentsCount
If not → add { id, commentsCount: 1 } to the array

Thanks you

You could put a switch in the commented event. If id exists go down that path (find object with that id and set new value), otherwise down the Else path and append new object.
