Rendering the entire component tree on every state change, even when only a small part has changed, can impact performance.

React Reconciliation: Understand React’s reconciliation process and component lifecycle to optimize rendering by updating only the necessary parts of the DOM.

Use shouldComponentUpdate: In class components, implement the shouldComponentUpdate lifecycle method to control when a component should re-render. class MyComponent extends React.Component { shouldComponentUpdate(nextProps, nextState) { // Compare nextProps and nextState // Return true or false based on the comparison }

render() { // Component rendering logic } }
