React Anti-Patterns and How to Avoid Them

React has become one of the most popular JavaScript libraries for building user interfaces, thanks to its flexibility and component-based architecture. However, with great flexibility comes the risk of falling into anti-patterns — common mistakes or practices that can lead to performance issues, maintainability problems, or unpredictable behavior. In this article, we will explore some of the most common React anti-patterns and how to avoid them.

What Are Anti-Patterns?

Anti-patterns are recurring practices that may seem effective at first but lead to negative consequences in the long run.
