Echo JS 0.11.0

This originally linked to a plagiarized version of this article, I replaced the link to point to the original article.

As the poster refuse to understand we do not accept plagiarized content or summaries, this seems to be the nicest solution at the moment :-)

So sorry, I honestly  didn't read  the policy of the site or the comments. From now on, I'll be more careful.
(but note that for each no original article posted,  there is the original source at the bottom :-D)
