[@diegocevallos5504]

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]

thanks xavier

[@kezevraanwar2]

You’re teaching is so straight to the point 👍🏾👍🏾

[@pcost]

Really good video! I love those small knowledge pills a lot.

[@mostafakheder7721]

Wonderful thank you for your nice explanation ❤

[@antonpetrov145]

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

[@tdbnz123]

Great video Love from New Zealand Thomas

[@adolfomartin5456]

Can we use private static variable for implement the singleton?

[@tasmto]

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

[@alivaliev5152]

What theme are you using? It looks gorgeous

[@eleah2665]

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

[@freemancharles2491]

Nice video as always, still eating my popcorn 😅❤

[@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?

[@Yardan_gholi]

i have a question please , iam learning to become a front-end developer iam almost about to finish j.s and i want start react after it , but it make me so hopeless when i see after learning one thing something new comes up to learn clear road map like leraning html /css and j.s and react and typescript is ok and understandable but ... now i see there are too many other things like the pattern design and also microservices and Agile and scrum and MVVM and all these new things that i have no idea about them even what are those. ,give me an advice please iam relay confused and lost my hopes.🙁😟🙁

[@peristiloperis7789]

Seems like you're wanting the roadmap without knowing where you're headed. First, figure out where you want to go. Then, choose the shortest route. Learning all these things won't take you anywhere.

[@juanmacias5922]

@@peristiloperis7789 all the things he mentioned are front end lol

[@jimhawkins2483]

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

[@janjgaval]

can you update old tutorials How To Create a HTML Dropdown Menu | CSS Dropdown Tutorial like this with new css features or how create carousel with html css and js

[@developedbyed]

Yes I will

[@janjgaval]

@@developedbyed you are great man 🫂

[@juanmacias5922]

Makes me think closures are just a mutation of singletons lol

[@cooltv9943]

Hi dev i'm the first one

[@developedbyed]

Are you thoooo???? Hahaha

[@ThopX14]

very funny dude 😀

[@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

[@j.r.r.tolkien8724]

But doesn't this mean OOP sucks 😂
