Can we update state without setState?

In React, to re-render a class-based component with an updated state we generally use the setState() method. But instead, we can use other methods to re-render a component without using setState().

What happens if you directly modify the state using this dot state in a class component?

If the state is updated directly as in the example above, the component will not rerender since the state is compared shallowly. Additionally, the update may be lost if there are other state changes queued asynchronously using setState.

How to update state value in reducer?

The state is updated and managed by reducers. Reducers always have to return something even if its null ; they should never return undefined . If a reducers state is an object, you must always return a new object instead of editing the object in place.

How to modify state in Redux?

For updating the state Redux is use dispatch(action). This is the one function used for making updates in the application. After this Store listens to the changes in the state. For this Redux used subscribe (listener) which sees the changes and updated state.

Why shouldnt you mutate state?

Yes, our contract (and Reacts one) is to treat state as immutable object. So, you shouldnt mutate state object. You can only replace it with set() . Mutating state can go wrong and break some behaviors.

Can you modify state directly?

If you modify the state directly, React may not detect the change, and your component might not re-render as expected. Potential Bugs: Modifying the state directly can introduce subtle bugs that are hard to track down.

How to modify React state?

State can be updated in response to event handlers, server responses, or prop changes. This is done using the setState() method. The setState() method enqueues all of the updates made to the component state and instructs React to re-render the component and its children with the updated state.

Why not modify React state directly?

If you mutate the state directly, React may not detect the change and fail to update the component properly. 2. Immutability and Immutability Benefits: React promotes the concept of immutable data. Immutable data means that once created, the data cannot be changed.
