Comparison of languages.

gistfile1.txt

Earlier I said Haskell/Scala/Python/Ruby/CoffeeScript are all pretty much the same.
By that I meant you can write much the same code in all of them, just the syntax might look a bit more weird or arbitrary in some cases.
Of course there are fundamental differences in the type of things you write in static versus dynamic languages, just as there are fundamental differences between what you write in a lazy vs eager language.

Print the numbers one through ten:

Python:
for i in range(1,11):
  print(i)

Ruby: 
(1..10).each {|i| puts i}

CoffeeScript:
[1..10].forEach (x)=>console.log(x)

Scala:
1 to 10 foreach println

Haskell:
mapM_ print [1..10]

See?  Just some syntax futzing, but same damned thing (ok, the idiomatic Python is different, and some don't permit eta reduction, but close 'nuff).

Of course, Haskell also lets you sequence your IO with things like:
foldr ((>>) . print) (return ()) [1..10]

A dumbed-down explanation of that line:
It could also be written:
foldl (\f i-> f >> print i) (return ()) [1..10]

which you could squint and think of as:

foldl( {(f, i)-> f(); print(i) }, noop, [1..10] )

You forgot JavaScript! How could you forget the greatest language ever! But JS you can do it whatever way you want:

for(x = 1; x < 11; x++){
  console.log(x); 
}

or

var x = 0; 
while(x < 10){
  x++;
  console.log(x); 
}

Or, i guess:

var x = 0;
do {
  x++;
  console.log(x);
}
while (x < 10);
