I just asked a question about return and it seems to do the same thing as break. How do you use return, and how do you use break, such as in the actual code that you write to solve the problems that can use these constructs.
I can't really post examples because I don't know how to use these so they wouldn't make much sense.

In Ruby, we use a break statement to break the execution of the loop in the program. It is mostly used in while loop, where value is printed till the condition, is true, then break statement terminates the loop. In examples, break statement used with if statement. By using break statement the execution will be stopped.
Ruby methods ALWAYS return the evaluated result of the last line of the expression unless an explicit return comes before it. If you wanted to explicitly return a value you can use the return keyword.
Ruby return StatementThe return statement in ruby is used to return one or more values from a Ruby Method.
To break out from a ruby block simply use return keyword return if value.
Return exits from the entire function.
Break exits from the innermost loop.
Thus, in a function like so:
def testing(target, method) (0..100).each do |x| (0..100).each do |y| puts x*y if x*y == target break if method == "break" return if method == "return" end end end end To see the difference, try:
testing(50, "break") testing(50, "return") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
