"return" statement and value in a method

A method is equal to its last evaluated statement. For example,

def some_method
  name = "Andrew"
end

some_method
=> "Andrew"

'return' is used when you want to return a value 'now' and exit the method. So, here it would make no difference:

def some_method
  return name = "Andrew"
end

some_method
=> "Andrew"

'return' is used a lot, because often you want to exit a method early, eg:

def some_method(name)
  if name == "Andrew"
    return "You are Andrew"
  end

  puts "You are not Andrew"
end

some_method("Andrew")
=> "You are Andrew"

# Method without 'return':

def some_method(name)
  if name == "Andrew"
    puts "You are Andrew"
  end

  puts "You are not Andrew"
end

some_method("Andrew")
You are Andrew
You are not Andrew
=> nil

When you start writing real methods of your own you'll find out how important and frequently used 'return' is. If you need anymore explanation, give me a shout. I recommend you play around in irb to (did you know you can write methods in it and execute them? Try it in workspaces.

Hi Andrew,

Thanks for your reply and explanation! It was very clear to me. I made this small code and and I wonder if I used "return" the right way. Would you please check it for me ?

I also have a question about a calling a method. In this code below, when I call the first method (name) and run the code, It will ask me twice " To enter the name", and when I don't call it, It only ask once! But I learned that every method should be called, isn't that right?

Thanks for your time and patients!

'''

def name

print 'Enter your name?'
name = gets.chomp

end

def adress

print "What is your adress #{name}?:"
adress = gets.chomp

if adress == "Leiden"

    puts"#{adress} is a very nice city"

elsif
    puts "I don't know were that is but that's no problem.\n" 

end

end

def cars

print "I heard you like cars! Is that true? (yes or no): "
answer = gets.chomp

  if answer == "yes"
        print "how many cars do you own? "
        cars_amount = gets.chomp.to_i

    elsif answer == "no"
  return    puts"Too bad"

end


    if cars_amount >= 3
            puts" Wow, that a huge collection"

    else cars_amount <= 2
            puts"Hhhmm you should buy more cars"
    end

end

name adress cars '''

Sorry for the weird post. It's my first time posting a code and don't know yet How I am suppose to do it :(

Hey Andrew, I found a way to sent the code as one whole. Check this link out

It's a online code interpreter!

hope to hear what you think about the code!
