How does reactivity work in React?
An example of an AI chatbot conversation about reactivity in React.
Can you explain how reactivity works in React?
Sure! Reactivity in React is primarily driven by state and props. When the state of a component changes, React re-renders that component and its children.
What triggers a re-render in a React component?
A re-render is triggered when the state or props of a component change. This can happen through user interactions, API calls, or any updates to the component's data.
How does React optimize re-renders?
React uses a virtual DOM to optimize re-renders. It compares the new virtual DOM with the previous one and only updates the parts of the actual DOM that have changed.
Can you give an example of state management in React?
Certainly! You can manage state using the useState hook. For example, const [count, setCount] = useState(0); allows you to track a count value and update it.
