You should be able to do this without JavaScript by using streaming.

Loop with range question

From: "Scott H." <lists@...>
Date: 2013-06-11 16:04:17 UTC
List: ruby-talk #408138
Hi All, working through understanding loops.  Would someone explain why
I cannot use =E2=80=9Cnext if i=3D3..6=E2=80=9D or =E2=80=9Cnext if i=3D(=
3..6)=E2=80=9D  in code below.
After each I inserted what I thought I should see as a result versus
what I did get returned. - Scott
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
i=3D0
loop do
 i+=3D1
  next if i=3D=3D3
  print "#{i} "
  break if i=3D=3D10
end

expected =3D> 1 2 4 5 6 7 8 9 10
actual =3D> 1 2 4 5 6 7 8 9 10
(yeah!)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
i=3D0
loop do
  i+=3D1
  next if i=3D=3D 3..6
  print "#{i} "
  break if i=3D=3D10
end

expected =3D> 1 2 7 8 9 10
actual =3D>  warning: integer literal in conditional range
(don=E2=80=99t understand, thought it was telling me it does not work bec=
ause it
can=E2=80=99t transform the range on the fly to the actual integers 3,4,5=
,6)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
i=3D0
loop do
  i+=3D1
  next if i=3D=3D (3..6)
  print "#{i} "
  break if i=3D=3D10
end

expected =3D> 1 2 7 8 9 10
actual =3D>  1 2 3 4 5 6 7 8 9 10
(so I thought by wrapping the range in a =E2=80=9C()=E2=80=9D it would co=
nvert to
3,4,5,6 and then be able to jump over these integers on output)
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
