Error while sorting array of objects Cannot assign to read only property '2' of object '[object Array]'

Question

I\'m having array of objects where object looks like this (values change):

   {
     stats: {
        hp: 2,
        mp: 0,
        defence: 4,
        agili         


        

Answer 1

To be clear, the issue is not purely that the array is frozen. Frozen arrays can be iterated over. As noted in ReactJS - sorting - TypeError: 0 is read only, the issue is that Array.sort sorts the array in-place, meaning it attempts to mutate the array. That's why you need to pass it a mutable copy of the array.
