Great explanation with clear figures! I do have one suggestion though for the last example:

// setTimeout(”loadFiles();”, 5000);
setTimeout(loadFiles, 5000);

Passing a string causes setTimeout and setInterval to use eval() instead of just executing the code, which is less efficient and can lead to scope issues. The scope part doesn’t matter in this particular case but it’s never an issue when you pass a function, so it’s best to get into that habit anyway.

just a idea, IE’s running javascript thread is not controlled by you when use “importFile(’javascriptFile.js’);”
