Learn how to detect and resolve performance issues in React easily using the library Why Did You Render.
React is lightning fast. Often, it’s fast enough to make it hard to re-create performance issues in a sandbox on our machines. Consequently, we might believe that our web app will run smoothly, no matter what we do.
But it’s a trap. Developers usually use strong machines and internet connections to build web apps. However, our high-performance environments might hide from us performance issues that can hurt our users. Unlike developers, many of our users access our web apps using mid-tier mobile smartphones from locations with bad internet connections.
But your app’s speed and performance matter and have a major effect on conversion rates.
If we don’t analyze performance, because of our relatively strong machines and internet connections, we will not know about performance issues that hurt our users and subsequently hurt our conversion rates.
This article will present a sandbox with a performance issue caused by a small React anti-pattern. Then, I’ll show you how it can be detected using the library Why Did You Render and how to resolve the issue.
