This explanation is gold! I really like the fact that a randomly generated number is used to detect whether the singleton has been created or not.

I have read a lot of articles about this in hopes of understanding it clearly but this video sums it all up. Straight to the point! Thanks for this!

Crystal clear & straightforward example. Like it!

I was hoping to find an NPM module that implements all of this for a generic JSON data structure. But I guess implementing all of this internally to a project from first principals is probably a bit more flexible and powerful for the individual needs of a project / developer. Nice thank you for sharing!! :-D

Perfect. I like it. Thank you so much (y)

Singleton pattern in JavaScript is completely useless. Javascript uses the prototype pattern, with that in mind you can just create an Object (JUST AN OBJECT) and use it like a singleton class. One instance, no "new", no classes, less code, easier implementation!

This example is absolutely useless. I still have no clue how to use singleton in real life and why I want to use it. The code is taken out of empty space. Why couldn't you give some real life example?

dislike for flashing a giant jquery logo in my face in front of my jquery hating coworkers.

It's quite funny that I came to Youtube because I didn't get Addy Osmani's explanation and then I clicked one of the top results, it turns out to be a plagiarism of his Singleton Pattern section in Learning JavaScript Design Patterns.
