If companies hire a lot then it can not really be called dying.

Well - you have no guarantee that trends will continue.

"past performance does not necessarily predict future results" is they
say.

But for some of the the language part I can actually provide some history:

               18-Dec-2011         10-Nov-2015
Java             16135                16783
PHP               3328                 2804
Ruby              1661                 1910

Surprisingly little change in 4 years!

Job openings are just the demand side.

There is obviously also a supply side.

To estimate supply vs demand I will recommend that you look
at how long the job ads has been up.

long time => supply < demand
short time => supply > demand

You could also try and look at salary levels.

high => supply < demand
low => supply > demand

But even though that is what economic theory predicts then the
modern job market is rather complex when it gets to salary
determination.

Anyway - indeed.com gives the following average salaries:

Java         102 K$
JavaScript    99 K$
PHP           89 K$
Ruby         107 K$
Scala        120 K$
Groovy       112 K$

But if you want my subjective guess, then I think this more reflect the
type of developers choosing the languages than it reflects supply
and demand.

Or to be more specific: I don't think Scala being in the top reflect
that companies demand more Scala developers than there are available - I
think it reflects that the developers that master Scala are all top
developers (because it is not an easy language to master) and they
would get a good salary no matter what they chose to program in.

The "full stack developer" is in fashion right now.

But there is so much you need to know.

HTML, CSS, client side JS
a server side language
SQL
XML, XSD, XPath
JSON
general OOP
etc.

Guess so.

But it is relative easy.
