confusion with inline rescue

I am not getting any output:

can any one point me by saying where did I wrong?

ar = [1,2,3,1,5,3,"a","b","c"] e = ar.each_slice(3) e.size.times{|i| i = e.next; p i if (e.peek rescue StopIteration) == nil }

I want the output: ["a","b","c"] but getting nothing.

Here I have done:

ar = [1,2,3,1,5,3,"a","b","c"] e = ar.each_slice(3) e.size.times{|i| i = e.next;p i if !(e.peek rescue nil) } #=> ["a", "b", "c"]

I am not getting any output:

can any one point me by saying where did I wrong?

ar = [1,2,3,1,5,3,“a”,“b”,“c”]

e = ar.each_slice(3)

e.size.times{|i| i = e.next; p i if (e.peek rescue StopIteration) == nil

}

I want the output: [“a”,“b”,“c”] but getting nothing.

with the statement modifier form of rescue you can’t specify a type of exception to rescue, so when e.peek raises

(e.peek rescue StopIteration)

evaluates to StopIteration, which isn’t nil
