Introduction
CodePen (https://codepen.io/) has established itself as one of the most popular online coding environments, particularly for front-end web development. This review will delve into its features, usability, and overall value for developers of all skill levels.
Key Features

- CodePen Projects: For more complex development needs, CodePen offers a full-fledged IDE experience with CodePen Projects, supporting multiple files and more advanced project structures.
