Hi Ram,
your take on Clojure to JS translation seems very interesting to say
the least. Thanks for sharing your work.
A few points I tripped over while reading the example:
* Why are functions being defined as "join = function (...)" instead
of "function join (...)"? Does this make a semantic difference?
* "if { ... } else { ...} break;" is probably missing a semicolon
before "break". Don't trust JS' implicit semicolon-adding ;-)
* The whole function body is being wrapped in a "return function()
{ ...}()". Is this done in order to support implicit return? My guess
is that deeply nesting such constructs could become quite performance-
heavy due to the many additional function calls.
* Mozilla's JS 1.7 supports a let statement[1] with lexical scoping,
though implementation support outside of Firefox is scarce. Depending
on your target audience and performance requirements it could be
worthwhile to implement this as an optimization instead of using the
"function(){...}()" trick, but only if allowed by some flag,
like :features #{:let} or similar.
I'm going to take a deeper look into this once I have the time.
