Event Emitter vs Context API in React
An example of an AI chatbot conversation about event emitters and Context API in React.
What are the main differences between Event Emitter and Context API in React?
Event Emitters are used for handling events and communication between components, while Context API provides a way to share values between components without prop drilling.
When should I use Event Emitter instead of Context API?
Use Event Emitter for decoupled communication between components, especially when they are not directly related. Context API is better for global state management.
Can you give an example of using Event Emitter in a React app?
Sure! You can create an EventEmitter instance and use it to emit events from one component and listen for them in another, allowing for flexible communication.
What are the performance implications of using Context API?
Context API can lead to unnecessary re-renders if not used carefully, as any change in context value will re-render all consuming components.
