Question

What is the best way to iterate an array, validate each element and then return does this array is valid in Ruby? Something like:

def arr_valid?(arr)
  result = true
  arr.each do |element|
    result = false if
       # validate element with some requirments
    end
  end
  result
end

I think there is a lot of code for this approach above.

Answer 1

Use all?, which will return true only if the block is true for all elements.

def arr_valid?(arr)
  arr.all? do |element|
    # validate element with some requirments
  end
end
