[Ottawa_users] Node

[Amos Hayes]

Can you provide some context on the discussion that prompted your
investigation? We have been using Javascript in the browser for Geo stuff
for a long time now. node.js wasn’t around when we developed the bulk of
our server-side tech.

Javascript is very fast these days, even in browsers. The trick with
browsers is to not touch the DOM until you have to, and try to avoid
unnecessary reflow.

See this for some good guidance.
