Convert an array of integers into an array of strings in Ruby?

Question

I have an array:

int_array = [11,12]

I need to convert it into

str_array = ['11','12']

I'm new to this technology

str_array = int_array.map(&:to_s)

user_61151 · Answer

str_array = int_array.collect{|i| i.to_s}

Start up irb

irb(main):001:0> int_array = [11,12]
=> [11, 12]
irb(main):002:0> str_array = int_array.collect{|i| i.to_s}
=> ["11", "12"]

Your problem is probably somewhere else. Perhaps a scope confusion?

Returns Int

x = [1,2,3,4,5,6,7,8,9,10] # => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

y = 1,2,3,4,5 # => ["1", "2", "3", "4", "5"]
