IE + JavaScript Performance Recommendations

[RonPK]

There's an interesting post on the IE blog on optimizing J(ava)Script code.

[blogs.msdn.com...]

[..] this blog will be the first in a 3 part series focusing on developing performance optimized scripts for web pages, covering the following:

1. Symbolic Look-up recommendations
   
2. JavaScript code inefficiencies
   
3. Script and performance considerations specific to Internet Explorer

Very interesting (and useful). I didn't realise that IE made so little effort on their side to keep code running fast (i.e. caching recent lookups).
