I have never seen real world ActionScript code which uses strict equality for null.
The argument to use strict equality “because of modern js advice” is not a reason to use it in ActionScript. The whole argument is to avoid unexpected type conversions. If you are dealing with typed variables, that is generally not an issue. Justin raised a valid argument to initialize Booleans and Numbers. It should not be taken any further than that.
