During React development, engineers may encounter several types of errors that can occur during the process. Familiarizing yourself with them can help developers quickly identify and fix problems. Here are some of the most common types of errors in React. UI bugs. React applications are built with reusable components, which means that the user interface doesn't always look as expected. While debugging ReactJS apps, UI bugs are usually easy to spot, as you can visually notice when something doesn't appear quite right on the screen. Examples include elements such as buttons or the overall layout. Logic errors. These bugs are tied to the logic and behavior of the React application and can lead to inaccurate calculations, unexpected behavior or improper handling of data. Logic errors can result from incorrect conditional statements and erroneous data manipulation. Networking errors. These bugs occur when a network request fails, resulting in an incomplete or delayed downloading of one or more resources. This can happen when you make requests to your own server or when you retrieve third-party assets such as embedded content or static files stored in a content delivery network (CDN). Network bugs can also result from the unpredictable behavior of third-party services on which your React application depends. In such cases, you may need to work with the service provider to fix the problem or find an alternative service. Regression bugs. Regression errors are functions that performed correctly in the past but now no longer work, often after a new code release. React applications experiencing rapid growth are particularly prone to these types of bugs. However, through thorough testing, including regression testing and continuous monitoring, you can prevent causing regressions in already working features.
