An example of an AI chatbot conversation about the differences between raise and throw in Ruby.
What is the difference between raise and throw in Ruby?
In Ruby, 'raise' is used to trigger exceptions, while 'throw' is used for non-local exits from a method.
Can you give me an example of using raise?
Sure! You can use 'raise' like this: raise 'An error occurred' if some_condition.
And how about throw? When should I use it?
You use 'throw' when you want to exit from a block of code early, like this: throw :symbol if some_condition.
Are there any performance differences between them?
Yes, 'raise' involves more overhead due to exception handling, while 'throw' is generally faster for control flow.
