Well, in Ruby:
3.times do
puts "Hello John"
end
greeter = lambda {|name| 3.times { puts "Hello " + name}}
greeter.call "John"
The CoffeeScript example would be:
for number in [1..3]
console.log "Hello, John"
...and if you want to do it exactly as in the example, then:
hello = (name) -> "Hello, #{name}"
for number in [1..3]
console.log hello("John")
do three times print "Hello John end
I guess my point is that, if the goal is to target new developers, why show "advanced" topics (like method) for an example that doesn't even need it?
