Question

I want to extract certain values from one array and concat them into another empty one:

freqs=[1,12,4,15,7,8,11,5,6]
less_freqs=[]

This is what I’ve come up with.

freqs.collect{|x| x<9 then x.to_a{|y|less_freqs<<y}}

Perhaps a different method? And, I’m not even sure if then makes any sense.

Answer 1

Is this what you’re looking for?

freqs = [1,12,4,15,7,8,11,5,6]
less_freqs = freqs.select{|x| x < 9 } # => [1, 4, 7, 8, 5, 6]
