Some of the issues in using the useContext hook are:
Performance: The useContext hook can create performance issues because it causes components to re-render whenever the context value changes. If the context value is updated frequently, this can lead to excessive re-rendering and potential performance issues.
Re-rendering a component is an expensive operation that can impact the performance of an application, especially if there are many components that are subscribed to the same context. To reduce this, it is important to minimize the number of context updates and to make sure that they are only performed when necessary.
Implicit relationships: The useContext hook creates implicit relationships between components by allowing components to subscribe to a context and re-render whenever the context value changes. This means that if a component is using useContext to subscribe to a context, it is dependent on that context for its state and behavior.
These implicit relationships can make it difficult to understand how changes to the context will affect the components using it. For example, if a context value is updated in one part of the application, it can have unintended consequences for components that are subscribed to that context elsewhere in the application.
This can make it difficult to understand the full impact of a change to the context, especially if the relationships between components using the context are complex. To mitigate this, it is important to design context carefully and to understand the relationships between components that are using it.
