Apologies for the crappy video, I am in the process of uploading it to Vimeo and will update the above when done.

For now, it seems on Windows only, right click on the video and select show all.

Thanks,

I Jarav, very true. I added a short video above to show the flow of execution.

Yes, in this case, both will yield the same results. But suppose, you had defined isNimble as

function isNimble() { return;},

typeof isNimble == “undefined” will be false but typeof isNimble() == “undefined” will be true.

I undertand the point you are making about the scope chain, however.
