This is a great idea, more pattern videos would be nice

[@sandrinjoy]

you can keep the instance variable as a static variable inside the class itself. which is much more clearer.

[@ELMlKO]

cool video, one usecase for singleton is creating a database connections pool

[@freemancharles2491]

Nice video as always, still eating my popcorn 😅❤

[@adolfomartin5456]

Can we use private static variable for implement the singleton?

[@alivaliev5152]

What theme are you using? It looks gorgeous

[@eleah2665]

frameworks are polluting our brains. Yes! Patterns is a good topic. Thanks.

[@tasmto]

More of this please and OOOH I have the same wallpaper!!

[@BeepBoop2221]

One thing i hated about patterns at universities was they jusy say here are the patterns but dont show you how they are used.

[@Xomps]

What are the advantages of this?
If I export an instance of the class it works the same I think, so maybe the advantage is that it's only instantiated on demand?
Am i missing something?

[@SeraphicRav]

Maybe when coding for IE (if it does not supports modules) or when not using modules at all

[@developedbyed]

You are better off not using classes and take advantage of Javascripts prototypal inheritance. Like Seraphic said, you can just do modules

[@icetmzz9074]

does anyone know what theme he's using?

[@anasouardini]

I don't get it; if you only need one instance, then why the construction?

[@jimhawkins2483]

can i ask for a desktop image?) thx in advance)

[@cooltv9943]

[@developedbyed]

[@janjgaval]

[@developedbyed]

Yes I will

[@janjgaval]

@@developedbyed you are great man 🫂

[@juanmacias5922]

Makes me think closures are just a mutation of singletons lol

[@ThopX14]

very funny dude 😀

[@j.r.r.tolkien8724]

But doesn't this mean OOP sucks 😂

[@coder_one]

Every time I see someone pushing class-based OOP into JS, it makes me want to cry....
Everything you want to achieve in programming can be done by programming functionally, and it will be safer, easier to maintain and more fun to work with

[@sonilpro8526]

Until you try programming something that is not a high school project
