This article doesn't seem to address continue, return, and break. These are control-flow features that are often allowed in blocks (though not all languages) that can't be done in a function. That is, in a block "return" will return from the enclosing function, and continue/break are a sort of signal to code calling the block. You can simulate the second, like jQuery.each(function (item) {if (timeToStop) return false}); but I don't know of good conventions for this so typically the functionality is skipped. But it's demonstrably useful functionality because it is so widely present in languages.
