.downcase? on word with upper and lowercase?

In this video it is explained to use .downcase so that if someone types in the words using uppercase letters, it will still return true.

What is the proper way to code if the word has both upper and lower case letters?

Example code 1 : print "Would you like to see your name Backwareds? (yes or no)" answer = gets.chomp.downcase

if answer == "yes" puts "this is your name backwards:" puts name.reverse

Example code 2: print "Enter name: " name = gets.chomp

if name == "Avi" puts "Cool! thats my name, too!" else puts "Hi #{name}!" end Example: response in workspaces: Enter name: avi
Hi AVI!

in example 2 it pulls the else statement instead of the if.

.downcase will work fine in this situation and is standard. I will replace all uppercase letters with lowercase and leave the letters that are already lowercase the way they are.

Thank you. However, when I tried that, It only seems to pull the else statement.

Code: print "Enter name: " name = gets.chomp.downcase

if name == "Avi" puts "Cool! thats my name, too!" else puts "Hi #{name}!" end

Workspace:
treehouse:~/workspace$ ruby control_structures.rb
Enter name: avi
Hi avi!

Should I change the "if name" ?

That's because when you call .downcase on gets.chomp it is returning "avi". "avi" does not == "Avi" which is why the else statement is running. the == comparison operator is case sensitive.
