Delete an item from Redux state
Just filter the comments:
case 'DELETE_COMMENT': const commentId = action.data; return state.filter(comment => comment.id !== commentId);
This way you won't mutate the original state
array, but return a new array without the element, which had the id commentId
.
To be more concise:
case 'DELETE_COMMENT': return state.filter(({ id }) => id !== action.data);
You can use Object.assign(target, ...sources)
and spread all the items that don't match the action id
case "REMOVE_ITEM": { return Object.assign({}, state, { items: [...state.items.filter(item => item.id !== action.id)], });}
You can use Try this approach.
case "REMOVE_ITEM": return { ...state, comment: [state.comments.filter(comment => comment.id !== action.id)] }
