You're optimizing a React application and notice that a particular component re-renders frequently, even though its props and state seem unchanged. Which tool or method can help you verify and prevent this behavior?
- Applying shouldComponentUpdate lifecycle method to the component.
- Enabling PureComponent for the component.
- Profiling with React DevTools.
- Using React.memo for the component.
In this scenario, you can utilize React.memo to optimize the component's re-renders. React.memo is a higher-order component (HOC) that memoizes a component, preventing it from re-rendering when its props remain unchanged. React DevTools can help you identify the problem, but React.memo is the method to prevent unnecessary re-renders.
