In the tutorial when i type this code into the console 

paper(14)
cls()
pen(11)
println("hello world")
sprite(153, 60, 60)
(It will only be their until after i close out please help)

if you want all is there, you should add into main.js in src

1.  Add pixelbox click Project > Open src
2. After new folder is open please open your main.js
3. inside main.js you can type your code

eg : 

exports.update = function () {
 paper(14);
 cls();
 pen(11);
 println("hello world");
 sprite(153, 60, 60);
};
