Discuss react profiler.
The React Profiler is a powerful tool built into React DevTools that helps developers measure and optimize the performance of React applications by tracking component rendering behavior.
Records render times: Measures how long components take to render during commits (updates).
Identifies bottlenecks: Highlights slow or unnecessary re-renders.
Visualizes rendering: Provides flamegraphs and ranked charts to analyze performance.
Install React DevTools (browser extension or standalone app).
Open DevTools (F12), go to the Profiler tab.
Click the Record button to start profiling interactions.
