Online Environments

There are a lot of tools available that allow us to write react code inside the browser. Using these tools, we can write react code that more closely resembles production code.


Codesandbox is nice in that it allows us to create a "virtual" filesystem and write code as if React's build dependencies are already pre-installed.

This tool is free and ready to use from the get-go and therefore is highly recommended for usage in building small react apps to understand the underlying principles governing this framework.
