Environment for JavaScript
Node.JS Environments
On the Node.js environment you will find the Description part, where are the requirements for the Challenge, followed by an example of the code that you are supposed to write. As well you will find the part where you can write your solution, with an initial code that is available for users. On the testing part, you will find the Run and Submit option, or the Unlock Solution, these options are for testing your code, or for helping you with the right answer if you have any problems resolving the solution. You can see the example of a Challenge that is with node.js environments in Fig. 1.

TIP
You will notice that on the Node.JS, solutions are shorter than on the Browser environment.
