Echo JS 0.11.0

Thank you for the critique about the English, indeed it is not my first Language. My native languages are Romanian and Russian. 

I experience a bit of difficulties when writing in English: but I am learning from my mistakes and I hope to improve after more writing practices.  

I would be glad to receive the list of fixes to dmitri@rainsoft.io

The article meaning is not to present the events in chronological order. Exists situations when series of events are related to a specific technology. For example the XMLHttpRequest, so I decided to group them by that to accentuate the importance for JavaScript advancement. 

Thank you for the constructive critique.
