What is change detection in React?
An example of an AI chatbot conversation about change detection in React.
What is change detection in React?
Change detection in React refers to how the framework identifies changes in component state or props to update the UI efficiently.
How does React determine when to re-render a component?
React uses a virtual DOM to compare the current state of the UI with the previous state, allowing it to re-render only the components that have changed.
Can you explain the difference between state and props?
State is managed within a component and can change over time, while props are passed from parent to child components and are immutable.
What are some common performance issues related to change detection?
Common issues include unnecessary re-renders, which can be mitigated using techniques like memoization and shouldComponentUpdate.
