Did you know it's not actually required? You're required to let the parser be able to distinct the keyword from an identifier. This goes for all literals/operators. If the parser is able to do that, then the whitespace is not needed. These are all valid statements, which do exactly as you'd expect them to. void""; void[]; void"moar"; ... return[some,array]; etc. (I'm still in favor of adding the space! But in terms of the spec, the space is only required to make a distinction.) - peter -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/[email protected]/ To search via a non-Google archive, visit here: http://www.mail-archive.com/[email protected]/ To unsubscribe from this group, send email to [email protected]
