Both procs and lambdas are stored blocks but syntax and behavior differs slightly.
A lambda returns from itself but a proc returns from the method it’s inside.
def method_proc
thing = Proc.new { return 1}
thing.call
return 2
end
def method_lambda
thing = lambda { return 1}
thing.call
return 2
end
puts method_proc # => 1
puts method_lambda # => 2
Notice that method_proc returns 1 because calling the proc ends execution within the method.
