Code HELLO WORLD.

Question

Why does the code already show up and work? We cannot do it our selves.
Please tell us why it is that way.

Answer 1

Examples are very good way to help learner to understand the topic.
Pressing Try yourself gives the program already for learner to modify it and learn about "what happens when he modified it like that", you will be able to write the program from blank by 2 ways:
1 clear the code.
2 quit the lesson and go to playground section and make a new program.
