What are context hooks and how do they work in different frameworks?
Context hooks are functions that allow you to manage state and context in various frameworks like React, Vue, and Angular. They enable components to share data without prop drilling.
Can you explain how context hooks differ between React and Vue?
In React, context hooks like useContext
allow components to subscribe to context changes. In Vue, the Composition API provides a similar feature with provide
and inject
, but the implementation and usage patterns differ.
Are there any performance considerations when using context hooks?
Yes, using context hooks can lead to unnecessary re-renders if not managed properly. It's important to memoize context values and use selectors to minimize performance impacts.
Can you give an example of using context hooks in a React application?
Sure! In a React app, you can create a context with createContext
, then use useContext
in your components to access the context value, allowing for shared state management.
