Hello jQuery :)

I am a beginner in the language of jQuery and I know all the fundamentals :)

Comments script such as Facebook Comments 
Add a comment and show comment quickly like Facebook without updating the page to add a comment or view the comment. 

I used the script, but it does not display a comment quickly like Facebook
