People end up choosing Elixir for one of two reasons:
- they identify with the Ruby-like syntax that they find familiar,
comforting or perhaps cool (it will always be a different reason for
everyone because behavior related to identity isn't rational). They
probably are/were Ruby developers or like Ruby.
- they require a feature that only Elixir provides. Survival.
Considering most Elixir developers come from Ruby (because of the first
point), Elixir has the most effort going into Web-development related
libraries, and so people coming because of point number two will most
likely use it for Web stuff (or Unicode, but it's usually Unicode for
(Some people are probably not going to be happy about me making the
above observation, but Elixir would grow a lot faster if they made use
of this instead of fighting it. The best way to make Elixir get big is
to advertise it as a better faster Ruby on Rails. Forget other
languages. Forget about Erlang. Just target Ruby people.)
Personally I don't really care about it. I am irrationally put off by
the syntax the same way I am irrationally put off by the Ruby syntax.
But even if I wasn't, it doesn't have any particular feature that would
make me want to use it. I guess you could use it to write DSLs, but LFE
is probably a better choice for that, in part because calling LFE from
Erlang is much easier than calling Elixir from Erlang, due to using the
same conventions for modules and types.
In the end it doesn't really matter. Use what works for you. Some people
are horrified by Perl, and yet there's still some large Perl codebases
out there, because it works for them.
On a related note, if you ask someone why they choose one or another
tech, you will almost always get completely different answers. The
reason is that the choice is rarely rational. When the choice *is*
rational it's because it wouldn't work with any other tech. But it's
rare because you can do most things in most languages. Same applies to
DBs, OSes... So people make the choices they identify best with (and
some people make a different choice every week because they identify
with tech that makes the most noise).
(Been talking about identity a lot recently, because I've been reading a
lot about it. The world makes a lot more sense when you realize *and
accept* that people are not rational, myself included.)
