Removing items

This works similar to how we insert items, except that we only create two slices and merge them together (with no item in-between). For the second slice, we skip one item after i to "delete" it:

const removeItem = (state = [], action) => {  const i = action.index  return [    ...state.slice(0, i)    ...state.slice(i + 1)  ]}
