    ECMAScript 5 is the current standard but as it has only just been finalised the browsers don't support everything in it. As far as I am aware ECMAScript 5 includes everything in ECMAScript 3 so if you learnt 3 first then you are well on the way to knowing 5.

    Few people actually set out to learn ECMAScript since it is only a part of what you get in any of the languages that are based on it. Most people learn an actual implementation of ECMAScript such as JavaScript/JScript in web browsers.

    Thanks so much for the reply, I'm already studying ES3 then I will progress in it with more confidence!!

    PS: All the modern books do teach digg first in the ES, then after it learn JS, and I'm not discarding to learn ActionScript!!
