Hi,
I’m quite new in Ruby. Here is what I wrote to convert array of
integer to array of string. I’m sure there is more compact and nicer
way to do this. Can I see the “ruby” way here ?
def convert(intArray)
stringArray = []
intArray.each do |i|
stringArray = stringArray + i.to_s.to_a
end
return stringArray
end
Thanks,

Thanks,
stringArray=intArray.map{|i| i.to_s}
map passes each value of the array to the block and puts what the block
returns in a array.

[1, 2, 3, 4].map{|i| i.to_s } #=> [“1”, “2”, “3”, “4”]
#map calls the given block sequentially with each item in the array, and
returns an array containing the values returned by those calls.
Cheers,

If you use Ruby on Rails or Ruby 1.9 you’ll also be able to do this:
intArray.map(&:to_s)
