FixNum#times is correct?

Ruby
1

irb> 5.times {|i| puts i}
0
1
2
3
4
5

Is it the expected output? I was expecting:
0
1
2
3
4

2

I think you may have clipped some of the output. Here’s what I get:

irb(main):005:0> 5.times {|i| puts i}
0
1
2
3
4
=> 5

It’s puts’ing 0-4, and then returning 5. To see this more clearly, try
this:

5.times {|i| puts “-- #{i}” }

The 5 you see is the return value of 5.times, which irb displays as it
does
with the value returned by each expression you evaluate. If you try the
above
code from a script or from command line, you’ll get the expected result:

ruby -e ‘5.times{|i| puts i}’

Ops, my IRB configuration is not helping me :slight_smile:

Thanks for the explanation.
