Ruby - Multiple ways to raise exceptions

Each of these lines will raise a RuntimeError 👇🏽

raise
raise "hello"
raise RuntimeError, "hello"
raise RuntimeError.new("hello")

How does the `raise` method work?

If the first argument is a string, it raises the RuntimeError with the string as an argument
If the first argument is the name of an Exception class, it raises the exception
Else, the first argument should be an object returns an Exception object when the exception method is called on the object. The object should look like this 👇

def exception
	Exception.new("hello")
end
