Most JavaScript code is also syntactically valid ActionScript 3.0 code. However, there are exceptions which leads me to my question:

Which constructs/features in JavaScript are syntactically invalid in ActionScript 3.0? Please provide concrete examples of JavaScript code (basic JavaScript code without DOM API usage) that is NOT valid ActionScript 3.0 code.
