codesandbox is an online code editor that allows you to create and share web applications quickly. it's particularly useful for react development, as it provides a simple way to experiment with code, collaborate with others, and showcase your projects.

getting started with codesandbox for react

here’s a step-by-step tutorial on how to use codesandbox for react development, along with a code example.
