Ruby: What's the difference between STDIN.gets() and gets.chomp()?

Question

What\'s the difference between STDIN.gets() and gets.chomp() in Ruby? Aren\'t they both retrieving raw input from the user?

side question:

Answer 1

because if there is stuff in ARGV, the default gets method tries to treat the first one as a file and read from that. To read from the user's input (i.e., stdin) in such a situation, you have to use it STDIN.gets explicitly.
