I'm completely new to Typescript (and javascript) and working with a key-value pair object.
Say I have state.itemsInGroup[numbers]
I have the following object which puts itemId 255 at position 1, itemId 254 at position 2, and itemId 251 at position 3.
{"1":255,"2":254,"3":251}
I need to put itemId 248 in at position 3 and increase the total number of "numbers" to 4, so that the object becomes:
{"1":255,"2":254,"3":248,"4":251}
How best to achieve this?
Object.values(state.itemsInGroup[numbers]).splice("3", 0, "248") does not change anything and still returns {"1":255,"2":254,"3":251} ???
state.itemsInGroup[numbers]["3"] = "248" replaces the value {"1":255,"2":254,"3":248} but I want it inserted and the existing value moved to "4".
Thinking about it I probably need an iteration to increase the key of 251 from "3" to "4" right? Go easy on me I don't really know what I'm doing lol.
