Course Content


One of the most useful talents a developer can have is debugging. It enables you to traverse your code correctly and rapidly identify issues. This is achievable on the modern web thanks to a variety of tools and strategies. React is one of the most popular front-end frameworks today.

You'll need to know how to debug your code if you're new to developing websites, writing programming, or just React JS. This article explains how to debug JavaScript using the Chrome Developer Tools and how to debug a React website using the React Developer Tools plugin.

Installing React Developer Tools can help you troubleshoot React more effectively. It's a debugging plugin for Chrome and Mozilla Firefox that supports React-specific capabilities. Open the React tab in your browser after installing the plugin. The Elements and Profiler tabs are worth noting.

Debugging is important in React because of the way it works. React uses a virtual DOM, which means that you can’t access any DOM elements directly. Instead, you have to use the data provided by React components to interact with them.
