Description
Some class methods, such as exists (for classes File and Dir) and iterator have been deprecated in favour
of exist and block_given respectively.
Bad practice
File.exists?(some_path)
Dir.exists?(some_path)
if iterator?
yield
end
Recommended
File.exist?(some_path)
Dir.exist?(some_path)
if block_given?
yield
end
