Environment for JavaScript
Browser Environments
On the Browser Environment, you will find the Description Part, this one will appear on both types of environments. The snipped with the expected output will be displayed under the description for this environment. Something different from the Node.JS type is the Preview Section, this one will show you the preview of your code. The Testing Options and the Initial Code where you can add your Solution are the same on the Browser Environment as on Node.JS.
