I don't think that encouraging scala code is good purely for maintenance
reasons. If there's a choice, it should be java. Not saying that learning a
new language is not cool - but in practice people are a bit put off by
maintaining Scala code. Its not only about what the writer of the code
prefers as a language: it's more important what the maintainers of the code
will has to work with.
Would such maintainers also be put off by new language features (lambdas)
in Java 8 when we (eventually) baseline to it? :-)
It's really NOT the same thing: any decent java programmer keeps up with
all the enhancements in Java.
What I might not want to - as an ISPN programmer - is to keep up with the
language enhancements in Scala. And I might need to do that because of
Scala language enhancements used in ISPN.
^ I wonder whether C programmers thought the same way 20 years ago.
Personally I don't believe Scala is the next big thing as it doesn't have
a "killer" feature, e.g. OOP from C -> C++ or GC from C++ -> Java.
That's 20/20 hindsight. Lots of C developers said OOP was bullish*t when
C++ came about, and even today some C++ folks argue than GC is for losers.
:)
Not sure about C developers, but there are plenty of developers in the
functional camp who still say OOP is bullsh*t :)
And many of the GC arguments were only invalidated 10 years after Java came
out, as multi-core became the norm and the GC could use a "free" core.
As Alan said, I for one look forward to writing all my code in
JavaScript
but until that day there is a lot of innovation we ought to embrace.
Java's shown itself to be slow to grow and evolve. Oracle's acquisition
of Sun has sped things up a lot, but it still is behind the curve. There's
a good reason why Ruby, Python, Erlang and Scala are gaining popularity.
If you've ever spent any time writing extensive code in any of these
platforms you'd understand why.
Seriously, what do JavaScript, Ruby, Python, Erlang and Scala have in
common? The only thing I can think of is "they're not Java" :)
I think Python is just as slow to evolve as Java, maybe even slower. And
it's not just the language itself, but the community as well: Python 3.0
came out in 2008, yet not everyone is on board just yet (
https://news.ycombinator.com/item?id=5009484).
Scala seems to be on the other end of the spectrum, adding a truck-load of
features every couple of years. My feeling is the Scala guys haven't
learned that every new feature starts at -100 points yet:
