i love how john just uploads a big chunk of his paid courses on youtube for free. been following him since 2019. i have bought his react and node courses on udemy. such a selfless man 🔥

[@imdtap1448]

Same...He's hella cool. His teaching is clear and concise

[@hellokevin_133]

He's the absolute worst lol

[@yashjainme]

@@hellokevin_133 why do you think he is worst 😕?

[@ajaymishra-jg2qe]

This is just for marketing bro

[@hammedadeleke7798]

I just landed a job that requires typescript experience and this course came at the right time

[@thej_]

You don't know how much i need this course right at this moment. FCC you are a saviour for me

[@nasiffuad292]

Same here xD

[@Booyamakashi]

Me too, me too.

[@kaziprosper2229]

John is an awesome Teacher. When I set to learn Nodejs, I watch his videos and that has extremely helped me! Thank John, for the good work

[@khantanoliggg]

From yesterday night I was looking for typescript courses that could cover all the fundamentals and intermediate concepts and today I got this gem. THANK YOU XD

[@codesinger-zc3bm]

Started learning Typescript last week and the ones I have seen aren't this detailed. I hope to learn alot from this

[@eacardenase]

I learned programming with John back in 2021, and that helped landed me a job as a web developer that year. He's an absolute beast on his own.

[@shahirantalukdar2387]

Are you from CS background ?

[@eacardenase]

@@shahirantalukdar2387 no, I was a psychologist.

[@eacardenase]

@@shahirantalukdar2387 I'm a psychologist that switched career to software development.

[@firstlastcode]

I love how you explain every concept bit by bit. I have followed and learned a lot of content from you, and today I'm better SE. Thank you and the freecodecamp community

[@Booyamakashi]

This is pure gold. Im going to watch it couple of times. I recommend to pause and do challenges before watching the answer - it makes learning better. PS. There is custom speed setting on youtube, you can run videos at 1.1x for example.

[@jamielujan5640]

Just finished the 10 hour batch here. Great stuff and incredibly clear and helpful. You really do learn javascript so much better once you get the hang of typescript. Looking forward to repeating some of the challenges a few times. Thanks a ton.

[@sherazakrampro8099]

I really needed this course. Thank you so much ❤

[@thedevelopermind]

John is a great teacher.

[@CasualCosta]

Just what I needed. Thank you, John! Thank you, FCC!

[@th3ja]

Top notch content and instructor! Awesome as always FCC!

[@akshaykumar-xu2be]

Looking for a good full course and there it is.. What a timing.

[@AyushmaansinghxX]

I was about to start learning typescript from tomorrow and here you dropped this gem ❤

[@khantanoliggg]

Me too

No it's john

[@firstlastcode]

My favorite instructor is here

[@gregfredder8645]

I love John Smilga

[@serial_coder]

I just recognized him with his voice. My favorite Js/Node teacher John Smilga.

[@alexref955]

What’s wrong with his voice? I remember speaking him normally

[@serial_coder]

I think he is high on drugs.

[@oreyon9514]

Man, john smilga is really good teacher for me. His method is easy to follow up.

[@_stanlymathai]

And who the F are you?

[@oreyon9514]

great

We are not intimidated by DEVIN AI at all. We are feeling that new energy already.

[@soldishero_YY]

9 hours? OMG. Let's begin

[@omers.143]

I love you guys

[@hooho491]

Very good course but I'm overwhelmed by the amount of information overall, especially in React section. It's difficult to use all the information in a real project 😕

[@pabitrakumar4564]

Finally my wait is over😅

[@orlandoferazzani3639]

at 2:12:50 couldnt we set up the book type like this type Book = { id: number; name: string; price: number; discount?: number; };?

[@Not_Aran8276]

Yes you can, it’s just different formatting and if you use something like Prettier formatter, it’ll do it automatically.

[@GiftMthimunye]

CAN we PLEASE have FLET tutorial 🙏🙏🙏

[@juanmacias5922]

LOL I don't know if it's because I have a newer version, mostlikely because I'm using Bun, but my website crashed. 31:13 Edit: interesting, only diff is that vite is 5.2.0 for me, so I assume it was Bun that caused the TS error ha 32:23

[@ashieraslam]

Is it for absolute beginner ? Or one's should have knowledge of any sort of programming language?

[@juanmacias5922]

Knowledge of JS would probably help, try it out, see how far you get.

[@marg5019]

No Closed Caption I can't hear it.

[@Sonyemman97]

How do people successfully finish these courses? I want to escape tutorial hell and I find myself there whenever I start these courses.

[@ramatjyotsingh2643]

Stop watchin tutorial beside just some syntax and basic stuff then start building a project on your own , you'll learn alot that way

[@CasualCosta]

For me, it was watching 15 minutes a time and then trying to re-create what he did from memory and checking only if needed. I did it for his React projects and it took me 2 months to finish everything, but it really did teach me how the library works.

[@omogbemeiyere6475]

The legend himself John f*cking Smilga so happy you dropping this course man ❤❤❤❤🎉🎉🎉

[@allsparky]

2:16:02 omg he's so right

[@MehmoodHussain-lk2qg]

Do we need to know basic javascript for this course?

absolutely.

[@LokeshKumar-tk7ri]

what about Devin?

[@Famelhaut]

🚭

[@rodrigolopez-qi5ez]

Where is the second part of this course?

[@flash0p]

its paid you can look at his website codingaddict

[@viktorbutanski]

Two and a half hours in - loving it already. Does anyone know if this yellow marker showing the function scope like here kzbin.info/www/bejne/gHmoc2qIna96Z7s is an extension of VS Code setting?

[@deepakjoshi3347]

Nice voice

So this video isnt the full course?

It is a full course. But you can pay to get an extra project to build.

[@hellokevin_133]

Why does this guy sound like this? don't other people feel irritated listening to him? he's also a massive spammer, just tries his best to make his courses unnecessarily long.

[@knowledgetogo92]

sorry, but this is like listening to grandpa when he is almost dying. This is so slow and boring. AI will help me now to learn TypeScript....

[@Oncopoda]

Course should be called TypeScript for absolute beginners. 😴

[@muhammadyafizhambatubara461]

please don't talk about devin, its demotivated me
