Weird Ruby: Begin-End Blocks
- MrBra 12y agoI think this post-condition (begin-end while) loop is really similar to that of many other common languages. For example in both Java and Javascript you have: do { statement(s) } while (expression); which will execute the code in the block at least once. Why in Ruby would that be much of a surprise then? The only difference is that in Ruby you use "begin-end" (and not "do-end" which can be used to create a block only in some contextes). Please correct me if I am wrong.
