Echo JS 0.11.0

Added note in the title that it's a paid product.

FYI, the reason I have removed most of the articles posted for this product is that paid products are against the posting rules for the site (even if there's a free tier).  I also tend to remove articles that are focused on the paid product.

With blogs on paid product sites, I will be more lenient if the focus of the article goes beyond the product and offers more learning or material outside said product.

While the product itself may be cool, and well priced, it's still against the rules.
