Hash maps are a particular implementation of tagged collections. Twenty years ago I'd have called them property lists, because that's what they're called in Lisp 1.5. There have been object systems based on property lists at least that long... "hash maps" is jargon, an implementation detail that shouldn't be exposed in the language. > In Self, there is a meta-object protocol; JS doesn't have that. That's where Self has this dependance on the GUI and snapshots, it's reluctant to let go the class model from Smalltalk. Early Self was actually more template-like, but they've deprecated creating new methods in the language rather than through the GUI even though they admit it makes things simpler. > You might contend that these things come from where Perl borrowed > them, fine; I didn't contend that at all, rather I said that the good parts of Perl that have seeped into Javascript are primarily the things that Perl borrowed from other languages. > esp. considering Javascript was conceived > for the browser environment at a time when doing dynamic web > content meant doing Perl, period. There was no such time. By the time even the early web came along there were hundreds of good scripting languages already in wide use. People writing dynamic web scripts in Perl are, and always have been, doing so because they preferred to work in Perl. Not because there was any reason other languages were any less well suited to the web.There's stuff above here
