Need help signing up cloud 9

Hello All, I need help in signingup cloud9… where I got the below error…( though cloud9 is closed with creating accounts I used the previous version of it so that I could practice coding) or else Is there any editor where I can use the terminal to execute commands ( cd,ls, all basic unix commands) and node commands… as I am getting this error with vs code editor C:\Users\user\Downloads\Jyothi>node echo.js
(function (exports, require, module, __filename, __dirname) { echo(“Hi there!!”,10);

ReferenceError: echo is not defined

Having just the below code in js file while learning node js

echo("Hi there!!",10);

whereas it is working with cloud9…
