Because of the following reasons, it is never a good idea to change the state directly: If you alter it directly, executing setState() subsequently may just overwrite your changes. This is not changed when you directly update the state.
Event handlers, server responses, and prop modifications can all cause state to be modified. The setState() method is used to accomplish this. The setState() method enqueues all component state updates and tells React to re-render the component and its descendants with the modified state.
We can change the state without directly mutating it using setState(). As a result of the state change, the component will need to be re-rendered. However, we must exercise utmost caution when using it. When you don't use setState() correctly, you'll not only miss your aims, but you'll also have performance concerns.
