How do I check that all the elements of an array satisfy a condition?

Question

I'm using Ruby 2.4. How do I check if all elements of my array satisfy a condition? I have

cond = true
arr.each do |e|
  if e.nil? || e.to_i < 5
    cond = false
    break
   end
end

but I feel like there's a more efficient way to do this.

Answer 1

You can rewrite that as

arr.all? { |e| e.to_i >= 5 }
