[@alan-oq4vk]

Just discovered this guy. Amazing. Doesn't waste time. Doesn't try to be funny. No nonsense clear, solid info.

[@endlessia]

So far the best «Everything you need to know » for Typescript with React ! ❤

[@ByteGrad]

Glad you think so!

[@ardianhotii]

I think the same too , the best video for typescript I've seen

[@__mas]

Insanely good.

[@adamrodriguez7598]

Seriously the best typescript video I needed

[@wishmeheaven]

I was actually looking the for useReducer, useMemo, and useCallback when I saw the title "COMPLETE"..

[@VincentJenks]

Your videos are excellent - amongst the best. You move quickly, waste zero time, and get right down to brass tacks. No fluff, lame banter, etc. I wish all course authors were as sharp and succinct! Well done, I like your style.

[@anastasiiazh.9107]

100% agree, love that it is straight to the point, and examples are great and very clear.

[@jou3883]

Agreed. and my next compliment has nothing to do with the content - I genuinely think he's good looking. Not flirting though, just stating the truth about his appearance. He looks clean, tidy and healthy. If only majority of devs could take care of their health more. And his skin is flawless and glowing! Not sure if he used any filter when recording this vid, but nevertheless, tell me your secret @ByteGrad !😅

[@khaleelalhaji]

​@@jou3883😂

[@wishmeheaven]

Shouldn't the title "Complete" arrive with (at least) useReducer..?

[@MarkEdwardTan]

I agree. Straight to the point. Excellent presentation and explanation as well.

[@shadyheadstash]

You're really nailing a great balance of introductory learning videos along with advanced topics. I find myself on your channel organically all the time and always find what need. Awesome work!

[@armangohari6193]

Whatever you teach goes straight to my mind's knowledge base, without me needing to organize the information. Thank you so much!

[@sedmidivka]

what I like about your videos is that I feel like you know what you're talking about. I really don't like learning bad practices and many tutorials unfortunately teach those because nobody is perfect of course :D but I really like that it's doesn't sound like you are repeating something you've read yesterday but it is what you really know and understand and it isn't "just because" but it has a reason. thank you

[@kuldarkalvik0]

Been quite sick for the past few days and this calm to-the-point teaching approach is just the perfect way to pass time productivly. Keep up the good work!

[@gurpritsingh3164]

Came across your channel today and this is the second video I have watched. I must say this is gold standard. Thank you for the hard work you have put in.

[@quanghungpham269]

Thanks a lot my friend, there are tons of tutorials out there but there are also people who have the basics of JS and React already. Your videos are suitable for people like me, learning fast and simple

[@pooyadehghan17]

this is so complete ! thank you

[@femmyemmy691]

I had to learn all these the hard way on the job. I'm glad you are helping developers out with this stuff... Kudos!

[@alirezagarshasbi6557]

i appreciate the roadmap, where you started, continued and ended is just awesome, easy to learn and easy to remember. thanks alot.

[@zaxpeedy2852]

oh my god, thank you. this video is awesome, an hour of pure gold.

[@OvercomerIdemudia]

Just amazing! Thanks for sharing.

[@hell2force]

Really appreciate you sharing Typescript fundamentals in such an easy to follow way ! This will now serve as my typescript refresher.

[@RajakumaranChakaravarthy]

By far best. Am going to suggest this video to every one in my team or ppl i know who are starting with Typescript. Thank you ❤

[@maxstrootmann]

This is awesome! Thanks so much for the video and especially the timestamps.

[@davesmith7658]

Great Tutorial, your slower pace and soothing voice made it easier to understand most of these concepts. Too many tutors who just talk to quick and assume the learners pace is at expert level. 🙌

[@yananderson5864]

Thank you so much for this video. I recently started a job, and it requires typescript, and this helped me a lot, it's incredible

[@gosnooky]

Nice thing about tuples, you can unionize them for different lengths. If you accept 4 numbers for padding for [top, right, bottom, left] or 2 values for just top and bottom ([x, y]), say, you could annotate tuple elements: padding: [x: number, y: number] | [left: number, right: number, bottom: number, left: number], then compute your padding based on the array length.

[@supafast1314]

Crazy amount of value in this mini course, Thanks a lot 🙏

[@brancode404]

Best Typescript course so far. I've learned alot thanks a ton brother. :)

[@mangoherpson]

Love your method of teaching, straight to the point and concise. Subscribed.

[@treyrader]

I've watched thousands of youtube channels and bro i love yours the best! Not sure if it's beginner friendly per se but for me it helps validate my understanding. ensures me that i am not entirely thinking about things wrong.

[@throwaway-lo4zw]

ur voice, tone and pace makes ur tutorials way better to follow and understand than everyone else, am i the only 1 who thinks this ?

[@srii_entertainment]

exactly. today I started watching a random video in this channel and I loved the way he speaks and immediately I subscribed to it and shared it to my friends.....

[@internet_18.0]

meow

[@sudarshan_savvy]

You are the best tutor; you know how to teach concepts very well. I have taken many paid courses and learned from more than 50+ KZbin tutors, no one matches your teaching style. Perfect pace, not slow, not fast, just 100% perfect. Clear concepts with practical examples. Thanks. Your voice is relaxing but was bit low in this video.

[@max_masterius]

That's great, thank you ❤ Finally I understand

[@nchatu]

Definitely the best explanation that can easily be digested I got for Typescript generics.

[@rujinopy7746]

I learn about TS in this video more than spending a whole year by myself lmao , really good content as always!

[@HenryBabbage]

Epic video, it is rare to see so much info so clearly communicated. Totally enjoyable to watch and the perfect pace for getting started with Typescript. Thanks alot!

[@gmjitendra]

very lovely and described TS in react. Gr8 Thanks

[@aliplaysgtr]

Super clear explanations of Generics, thanks a lot man!

[@iqwebserve3973]

Fantastic refresher plus tricks.

[@sukhjindersingh7802]

Great in details and very easy to understand, Thanks a lot man ❤

[@bashkort_erete]

God bless you, man, thank you for the lesson👍👍👍

[@ts8960]

I like that you are opinionated and use the cleanest looking formats , keep up the good work

[@AlexBereza]

This is just awesome! You've managed to explain most of the Typescript in React in just 1-hout video!

[@meew7571]

great teaching bro. very helpful for as a react js developer trying to learn react typescript.

[@shivagurung4161]

Thank you ByteGrad!

[@julias3782]

Amazing quick explanations! I've watched the video in one breath. Thanks!!

[@santoshparker8681]

Awesome tutorial . Your channel deserves more subscribers. Just keep uploading videos. We are enjoying your content.

[@dxabraham198]

I would of loved to watch this video 4 years ago when i was looking for a new job and i applied for one in which typescript was a nice-to-have requirement and when i joined the project it turned to be a whole react/node project written in TS. Everything you explain along the video i learned it struggling and pulling my hairs off of my head lol. Now i watched your video out of curiosity and i can say it's the best "Everything you need to know" video i've seen according to my experience. You really nailed it!

[@daria_vyshniakova]

Wesley, thank you. This tutorial is amazing! I understand more from this video than from udemy TS course

[@deni930918]

Thank you for the valuable content in this video! I've been writing in TypeScript for quite a while, but I still learned a lot from watching it, and I recommend it to everyone. It would be great to make tutorials for creating a Next.js application from scratch. ❣👏

[@ivanyoed]

Thanks a lot man. Will be watching a lot of your videos. They're very well made. Sometimes a bit fast for me, but I can always pause or play them slower. Anyways, thanks for the hard work.

[@sharonmazor9531]

Great video!

[@minamulhaq]

You upload what I really need right now

Now that's what I call content! Awesome job!

[@nogafouz2174]

thanks alot for your super explaine

[@Kimi-xp2th]

I just recently started coding using Typescript and i really needed this. I re-coded one of my React projects using TS but Im not sure if i used it right. I got no errors but i still have some questions. Im sure this video will be of great help. Thank you.

[@CKNMEDIA]

Best one ❤

[@Cypekeh]

These latest videos of yours are overpowered

[@naimurhasanrwd]

This is best! You are extremely professional, experienced and also teach noob. Amzing.

[@programmingwithnit5308]

Thank you so much 🎉❤

[@Kaldaway]

Great Work ! Applause )

[@Yahya_Umar]

I enjoyed your videos! Do you have any plans to create a tutorial on building an inventory management system using Next.js? Your tutorials are fantastic, and I'd love to see one on this topic! I also want to include as well as utilize free APIs for data integration.

[@jsinnerx]

The best react with typescript video I've ever seen.

[@wishmeheaven]

Have you find those which called themselves "COMPLETE" as this one, But also include useReducer, useCallback and useMemo..? 👀

[@mohammadmehdikhani1398]

thanks buddy

[@khizer3528]

To the point nice explanation man ❤

[@katerynamordovtseva1191]

Thank you for your job!)) I have never get such good quality info in Russian or any other languages!

[@heysahilsingh]

Amazing, such an amazing content you’re putting on internet. I wish you a lot of success, ❤️

[@abdirahmanabdullahi1966]

you got my subscription and like, but i will watch this one in the near future.

[@developerpranav]

Such a thorough video. Thank you! This has so much that I didn't know before!

[@ByteGrad]

Glad it was helpful!

[@saiphaneeshk.h.5482]

Fabulous, just found the channel recently and helping me allot. Hopeing for more tips and tricks for reactTs.

[@ryanwoods3333]

Thank you for this! I really hope you publish more React + TypeScript content as there isn't enough of it on KZbin which teaches both together.

[@olusanyaolamide9764]

Exactly 💯, it's good to see videos like this, JavaScript mastery released a video recently saying React isn't NextJs and he talked about server components and how we must change the way we think when using the new nextJs 13 app router, the new changes can be a bit overwhelming especially for newbies just transitioning from react to nextJs, I still use the old pages directly for my learning for now, I feel the app router to be confusing

[@safariambience4052]

This is top-shelf educational content. Simple and easy to reference I have learned a lot. Thank you

[@ByteGrad]

Great to hear, thanks

[@liquidohr84]

Not sure if it's intentional but your video has an ASMR effect. The most relaxing coding video I've seen.

[@michaeldiaz7919]

Great Job , I enjoy every single section and explication in this video. Thanks so much!!! Keep Going new follower here

[@adembenabdallah9678]

I appreciate your work ❤

[@webdev_telugu]

His voice is so peaceful

[@hamadler]

Great video

[@isurumaldeniya9536]

Wow thanks. Learn a lot. specially the ReactNode and why we need to pass children to make it works. Thanks again 😊😊👍👍
