Weird Ruby: Begin-End Blocksblog.newrelic.com 5 pointstkrajcar11 years ago1 commentSaveHideCopy link On HNComments−MrBra11yI 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.

I 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 {
} while (expression);which will execute the code in the block at least once.
Why in Ruby would that be much of a surprise then?
