Can I get feedback on my JS documentation page

Code Feedback

I’ve completed the technical docs project, want your feedback to improve the project.
All the tests are passed. I’ve commented the script tag though.
Take a look and suggest some improvements if you have any.

Great job on the documentation man. One thing though, can you try to make all the example codes align to the left, because all of them are aligned to the center.

Ok, thanks for suggestion. Will update soon.
