In Ruby, there is an alternative to exceptions handling, and that is using the “throw/catch” system.
Throw/catch are specifically designed for getting out of nested loops.
For example, say of you are 4 loops deep, and you only want exit out to the second loop, then you can use throw/catch to do this.
Here’s an example:
catch :abort do [1,2,3,4,5,6,7].each do |number| while number == 5 puts number puts "need to abort infinite loop" throw :abort end puts number end end
The symbol “:abort” is used here in the sense of a label. It is used here to pair up the throw statement with the corresponding abort statement.
throw-catch even works across methods.
Throw/catch is just an alternative option you can use. But it’s unlikely that you will use it that heavily.
