which of the techniques that i listed that are common now dlwere possible then?
we did indeed squeeze a lot out of the code we wrote. and we were very aware of js performance issues- using array.join religiously instead of concatenation was a big one. but most of the modern techniques & concerns simply werent appplicable or possible.
the shift from writing it ourselves to loading dozens or hundreds of modules came quite late, all told. that lead to the explosion of performance tools & techniques.
