MERN stack technologies along with the whole full-stack development ecosystem are continuously growing and improving with increased adoption and usage in the industry. In this edition, we take these new developments into account and update all the applications and corresponding code bases from the first edition.
We use the latest versions and conventions of each technology, library, and module needed for both development-related setup and feature implementations. Additionally, we highlight the use of new features from these technology upgrades such as React Hooks, and JavaScript features such as async/await.
In order to showcase even more possibilities with the MERN stack, we updated the existing marketplace application to add a more advanced feature such as real-time bidding. We also add two new projects, a web-based classroom application and an expense tracking application with data visualization features.
To better understand the content and concepts covered throughout the book, we expand on explanations and provide leads to the latest resources that may help you get a deeper grasp and improve your learning experience.
Besides covering the latest updates to MERN technologies and providing elaborate explanations, the concepts and projects in this book are organized to help you learn from easy to advanced topics with the flexibility to start at any project of your choosing. In the next section, we will discuss the structure of the book and how you can utilize it based on your preference and experience level.
