Gah. Apparently you haven't spend much time reading the article.

Steve created it because he's creating a javascript mode for emacs,
with the goal of it being a full IDE beating any other javascript
IDEs.

That mode eventually became js2-mode.  The js interpreter engine was a
discarded by-product, because he ends up writing another engine. The
name “ejacs” was attached to it later, and became a separate project,
currently of little practical use.

Steve has hinted in his blog, that he has the goal of making js a
alternative to elisp for extending emacs.

yes but not really. JS as a scripting lang is used in lots of
applications, in Flash, and lots others.  (see wikipedia for full
list) Basically, it has became practically what Scheme used to be or
envisioned to be in academia, and replaced what perl, tcl, tried to be
in the industry in the 1990s.

Personally i think that's very good.
