Debugging Code and the React Developer Tools

Earlier in this chapter, you learned that component functions may execute quite frequently and that you can prevent unnecessary executions using memo() and useMemo() (and that you shouldn't always prevent it).

Identifying component executions by adding console.log() inside the component functions is one way of gaining insight into a component. It's the approach used throughout this chapter. However, for large React apps with dozens, hundreds, or even thousands of components, using console.log() can get tedious.

That's why the React team also built an official tool to help with gaining app insights. The React developer tools are an extension that can be installed into all major browsers (Chrome, Firefox, and Edge). You can find and install the extension by simply searching the web for "<your browser> react developer tools" (e.g., "chrome react developer tools").

Academind GmbH - Online Education: Bundling the courses and know-how of successful instructors, Academind strives to deliver high-quality online education. Online education, real-life success—that's what Academind stands for. Learn topics such as web development, data analysis, and more in a fun and engaging way. Maximilian Schwarzmüller: Since the age of 13, Maximilian Schwarzmüller has never stopped learning new programming skills and languages. In the early days, he started creating websites for friends and for fun. This passion has remained and shaped his decision to work as a freelance web developer and consultant. The success and fun he has in this job is immense and really keeps that passion alive. Although he started web development on the backend (PHP with Laravel and NodeJS), he has increasingly become a front-end developer using modern frameworks such as React, Angular, or VueJS 2 in a lot of projects. As a self-taught developer, he had broadened his horizon by studying business administration, resulting in a master's degree. This enabled him to work in a major strategy consultancy as well as a bank. Whilst learning and developing his skills, he realized that he enjoyed development more than these fields. As a self-taught professional, Max is familiar with the difficult topics when learning new or improving on already-known languages. This background and experience enables him to focus on the most relevant key concepts and topics. His track record is the best proof of that. Whether working as a development instructor or teaching business administration, he always receives great feedback. The most rewarding experience is to see how people find new and better jobs, build awesome web applications, acquire amazing projects, or simply enjoy their hobby with the help of his content.
