[haXe] best strategy to port an existing js library

[picnic]

hi
I'm trying to follow the discussion ...
if I get you right is a bit a question of type safety vs. JS performance.
A thought in that regards: Maybe it would be possible to implement
some type checking logic in haxe. Or working with "interface files" in
js that are not running the final JS code, but helping to test and
compile the code.
ok - its just a idea :-i
