React, a highly popular library due to its UI-first approach, has matured over the years, but developers often question the best practices to follow. While certain practices are generally accepted, they can sometimes compromise performance or readability. The article discusses five such practices in React that can be avoided and offers alternative approaches. It explains the default behavior of React's reconciliation process and suggests using the Profiler tool to measure performance and optimize by preventing unnecessary rerenders. Other topics include the importance of image and build file optimization, the role of server-side rendering (SSR) for SEO, alternatives to inline styles such as CSS-in-JS with styled-components, and the pitfalls of using nested ternary operators and closures inside render methods. Instead, the article suggests using class methods or the useCallback Hook to improve performance and readability in React applications.
