I was avoiding generics for a while for no reason, now, finally I will avoid it with a reason

[@patfre]

And now employers are gonna avoid you for a reason

[@jotasenator]

@@patfre auch! was a funny way to say the content is great and well explained but still generics are hard and verbose no matter what. Will be healthy a pole to show how many devs use generics in his job. Also if an employer doesn't select you because you don't use a specific content, well, that is not the place.

[@patfre]

@@jotasenator the whole point of generics is the make thing generic, they are very helpful in making things type safe especially with how much TS allows you to do, I just used it today to make my code simpler and cleaner and not be 100 lines of repeated code. Also the thing about companies is they want safe and reliable code that follows best practices a lot so they can absolutely deny you for something like this if your 100% not willing to follow their practices with the code

[@slimbofat]

​@@jotasenatormight as well just avoid typescript while you're at it. Generics are what allow effective code reuse and sound typing to coexist

[@jotasenator]

@@slimbofat the thing is I do use typescript, but never generics, in react.js and vue.js and next.js. I was watching this video because all the contents in here are explained in a way I like, still, don t see generics in the feature for me. Not saying I am against them, just I didn't find myself in a position saying: well, is time for generics...

[@ashishboora3049]

I am react developer and never used typescript, just out of curiosity started watching it. Now i am suddenly feeling like i know complete Typescript. I mean how well you explained it, i can understand every second of this video. This is really some next level teaching skill.

[@timlind3129]

Honestly - this is probably the best description / example I've seen yet! Keep it up!

[@ByteGrad]

Thanks, will do!

[@user-ie7md3mm6x]

agree 100%

[@mblackritter]

I've also to *SUPER AGREE* - it's like *finally* someone really explained how it works - instead of talking plain code! 😻 haha 😹💦

[@tomisadone1145]

Spectacular video, had it open in a side tab for a month and I can't regret more not watching it before. Clearest explanation I've seen in a while

[@xReDxTuRtLeZx]

thanks for the clarity. you are great at explaining concepts, your vids have objectively made me better at TS and feels great when i manage to remember parts of vids when i encounter scenarios on my projects

[@MrBrandenS]

Wow this video shed a ton of light on some of the confusing pieces around generics for me. The content was so well put together and with the real life example with usages in react itself it really drove the point home from your early examples of generic benefits and when ti use them. Amazing way to teach these concepts. Thanks! Subscribed.

[@fluntimes]

I agree, this is the best explanation of generics I've encountered. Makes them seem easy, so your video description is on point!

[@IrfanIdris]

I never realised generics are that simple to explain. Simply great! 👍🏽

[@xi_red4936]

This is hands down the best explanation I've ever seen on type Generics. Thank you soo much!

[@HeyNoah]

Awesome tutorial!! Super easy to follow! Thanks a mill!

[@ryanwoods3333]

really enjoy the typescript/react content thank you!

[@RegisZaleman]

Well done. It is one of the best explanations of generics I have heard. From super simple to using it in React. Really good. Got my sub!

[@raheelafzal5406]

it was the best of the best explanation i have seen. did not understand the generics, but now it all making sense. HUGE THANKS BRO

[@tblancog]

I really liked the way you explain such a complex topic like this one, you got a new subscriber. Thanks!

[@mohamed_mahran]

Thank you mate! The video was on point. Finally I got a understanding in generics.

[@patriciogesualdi7472]

I really like the emphasis on the relationship aspect, great video!

[@Harduex]

Very clean and comprehensive tutorial, keep up the good work 🙌

[@grottogg4758]

Thanks for all your hard work, extremely helpful teacher!

[@bcb3548]

As someone who has been anxious even when seeing cryptic type notations, this lesson is almost like a therapy session. For me, adding just after writing the function name make sense than coming back to it after annotating arguments. It reads like "this function / class is meant to work with these types".. Thank you!

[@ALI-se4ph]

your channel is great for junior devs who already know javascript and got job but they need more tricks and knowledge to become a better developer

[@lil10dot]

the way you explain is so clean and concise

[@uvaishassan]

This is the best video on generics I have watched so far. Was really struggling with understanding generics but this helped a lot. Explaining in terms of relationship between arguments and return type was brilliant

[@ardianhotii]

I think the same too , best video for generics , again thank you so much @ByteGrag for these awesome videos

[@ByteGrad]

Great to hear!

[@grzegorzpaprzycki2547]

You explain hard topics very clearly. Keep going like that ❤

[@matan1147]

Great video! loved your explanations 🔥

[@PaulnJenna]

Amazing! I was confused before watching this. Great explanation!!

[@fisayowatti7208]

"Hopefully this helps you out a little bit with generics". No sir! This helped me out a ton!

[@MarcosReis-ok4lv]

That is a great video, very well explained, thank you!

[@user-ie7md3mm6x]

You totally nailed it! I've read docs couple times and yet still didn't get full understanding, but now... thank you man!

[@ByteGrad]

Great to hear! :)

[@user-ie7md3mm6x]

@@ByteGrad great explanation, keep up the good work

[@saiphaneeshk.h.5482]

Damn, it feels difficult but you can no where find these kind of basic knowledge which you'll only get from experience. Thanks allot.

[@sofianesaid226]

easier than I thought now after watching your video, thank you very much!

[@mkaufmandev]

Excellent tutorial packed with valuable information and reasoning.

[@pixyoutube538]

Great! Your video is very easy to understand

[@sakarsr]

Neat explanation of Typescript Generics. Thank you for your time, have good health and a nice day.

[@user-zd1dt7tz1u]

This was such a good explanation. I was always wary of generics, but no longer!

[@nurlanshukurov3864]

This is the best Ts generics video I've seen so far. Please, make video about mapped types and keyof keyword also. 👑

[@pastuh]

If the React/Next.js course were explained like this, it would be amazing.

[@maor44]

Amazing video dude! really helpful!

[@Redyf]

Your videos are REALLY helpful, thank you so much

[@huykyoby1059]

Thank you, Can I ask what extension you are using that it suggests when you code?

[@shivanshpatel4072]

Awesome video you make this concepts really easy to understand ❤

[@tszhong0411]

You are the best! Keep it up ❤

[@heitorpaulo5403]

Wow! Finally...The relationship tip was the key to understand generics for me.

[@__mac]

This helped alot!

[@ethaneth6481]

In practice defining theme just as a string makes more sense, but I got your point, good tutorial

[@miksica]

Pure gold, and thank you!

[@SimPwear84]

Very cool video! I found your channel today and subbed for more content

Excellent presentation

[@Salah-YT]

thank you so much

[@scott98390]

Is there a way to create extension methods on a Type without running into issues because you extended the .prototype?

[@md.asifal-mahmud5952]

Awesome, Thanks a lot.

[@meal_team_six]

Very helpful!

[@mervinmarias9283]

I don't even use TypeScript, but after this video I actually understand how to use generics.

[@shashanktiwari8511]

Excellent example, and i want to know what is this VS extension that is giving suggestions for auto code complete

[@iwmatt]

[@shreyas0924]

Greate video!!

[@123tomani]

Very well explained 🎉 Can you also do a video on websockets and best way to implement in micro front end application

[@nathpaiva]

Generic is so cool. Nice video!

[@sergio.808s]

thank you!

You're a beast man

[@K.Huynh.]

thank for sharing! It's new for me! 🌈

[@kaushlendrashukla8350]

Well explained

[@Landersaki_]

what theme you use?

[@isaiahdavis.com_]

For the createArrayPair can you also use the reserve word argument if the function name itself is explicit enough and your parameters are not a specific data type?

[@mikkun_]

In just 22 minutes, I've learned a lot

[@raymondmichael4987]

Thanks buddy 😊

[@ByteGrad]

No problem 👍

[@cubedev4838]

I love how the way u explain

[@demimontalto]

Great! Just one question: what's the point of having a generic since you are extending it from something else (React.ReactNode in your example)? You do that just for relationships between params and return value or am I missing something? Thank you, keep it up!

[@ByteGrad]

Yep, just to codify that relationship between the 2 props

[@attilagyen1446]

You can make it more clear when you leave out the { } and make the convertToArray as a one-liner. const convertToArray = (input: T) => [input];

[@Ultrajuiced]

Just remember that it won't get hoisted.

[@ChiragGoyal777]

This is impressive, First time having a cool way to learn Generics. Keep it up! :) Please make a video on key of generics using

Best best ts teacher on youtube

[@schintus]

As a C# developer, this might be easier for me to understand up-front than pure JS devs :)

[@lp26197]

Hello my friend, I am following you and I want advice from you. I am a front-end developer and I use next js and I have worked on actual projects and I want to start in the back-end field. You advise me to start with C# or Javascript framework and work. I am very confused. Please help me. From your point of view, what is best?

[@antonarbus]

Очень хорошо объяснил.

[@MrEnsiferum77]

How do I use generics in some generic component like Table, when I need the id property, for filter let's say... in that case Typescript complains that can't find the id on T type, so I must add intersect with & { id: string }, so I can help Typescript to infer the id type.

[@doniaelfouly4142]

thanks

[@anspangilinan]

Superb
