QUESTION
I'm using mobx-react / mobx-react-lite for state management
Using classes i can define a non observable idToDelete to store the clicked item id, open a Modal using an observable and when the user clicks "Delete", i know the item to delete. The id is "remembered" by the component trough the re-renders
...ANSWER
Answered 2019-Jun-13 at 19:37You can use the useRef hook to save the value. A change to this value will not trigger a re-render and the value will remain the same across renders unless you override it.
Its also explained in detail here
Yes! The useRef() Hook isn’t just for DOM refs. The “ref” object is a generic container whose current property is mutable and can hold any value, similar to an instance property on a class.
