I agree that changing the behaviour makes sense. But what if we wanted to maintain the behaviour, what name could we give to that behaviour. cannot reassign but can modify.

We could follow the path taken by Elm and their awesome error messages like:

I saw you used a constant here:

const fruits = [...];
      ^
      |
     here

It seems like you tried to update one of its member:

fruits[0] = ...
       ^
       |
      here

I think that you might wanna use Object.freeze to prevent causing side effects

const fruits = Object.freeze([...]);
