External REST API Integration, Avatar Management, and Jest Testing

Welcome to the fifth homework assignment in the Fullstack Bootcamp, where we continue to build upon the foundation laid by our previous projects, especially those emphasizing HTTP requests. This module signifies a shift in focus towards more advanced features. In this stage, we explore the integration of sophisticated functionalities, such as the ability to add avatars for users upon creation. This enhancement not only adds a personalized touch to user profiles but also enriches the overall user experience. Additionally, we delve into the world of Jest unit testing, ensuring the reliability and robustness of our application. This step reflects our commitment to delivering high-quality Fullstack solutions. As we integrate these innovations, we look forward to the unfolding possibilities on our journey of continuous skill development.
