React applications can sometimes experience performance issues due to unnecessary re-renders and inefficient state management. Fortunately, there are several tools to help developers analyze and optimize React component performance. This article will cover three essential tools: React Profiler, WhyDidYouRender, and useTrackedEffect, providing insight into how they work and how to integrate them into your project. The React Profiler is an in-built tool that helps developers measure the performance of React applications. It tracks the rendering time of components, the frequency of re-renders, and the cost associated with rendering, enabling developers to identify performance bottlenecks.
