Software Engineer using React daily for 6 years now and this is hands down the cleanest explanations of those concepts I ever saw. Sharing this everywhere.

it is clear for you because you were already working for six years on React

This is the most cleanest and concise explanation of react concepts ever

"class" to "className" isn't to make it camelCase as "class" is already camelCase. It's to avoid conflict with the JS keyword "class" for creating classes.

You can't decalre a class inside JSX though. You can also use this seemingly reserved keyword between JSX tags, like class. React team can update their JSX parser to allow using the "class" and "for" attributes, but I guess it isn't really a pressing matter.

@@szyszak when you write class you're telling put the string "class" inside a tag. when you want to escape into javascript world you need to use the brackets { } so try writing { class } now you'll get an error since class is a reserved keyword in javascript and React is just Javascript end of the day.

​@@nivethan_me when you write className in JSX, you're doing it inside , which also should tell the parser you're not using the class keyword. It's an arbitrary change

Awesome content, as a backend engineer that is starting dealing with React, this is pretty straightforward and saved me a lot of time.

Man, this was the best class I've ever had on everything I learned in programming. I already knew most of the concepts but the simple way you exemplified was excellent. I will watch your other videos.

Best video ever to brush up most of the react concepts 😊

Molim se da vaša velikodušnost prema nama bude nagrađena. Ovaj video je odličan poklon

This has to be the best react speed run ever means a lot bro thank you.

I'm a senior Angular developer, but wanted a quick way to pickup React, and I have to say this video is amazing, it doesn't get hanged up on the details and explains the concepts with text and examples, along with the reasoning as to why it's implemented this way, in addition you referenced the most used common patterns which is a great touch Just a great video!

great work man,I just revised react in 11 mins,Keep growing!!

Using index as a key is ok for rendering UI derived from an array that doesn't have to change the order of it's elements. But when you have an array that does change the order of it's elements you gotta use a unique key (usually the id of that data item coming from the DB)

Very smoothly explained and so clear and concise.

You have a unique way of explaining things. Keep up the good work!

The best video on React! Extremely clear and concise

Great video! I love how you added a bit of Foley as well. 💯

Awesome video. Especially for someone who worked with React before and needed some kind of refresh.

lol i been teaching my self react for 2 years and this just put all the pieces together for me so well haha.

I love it. you have exceptional content creational skills

Learning React for 2 weeks. Your video really helped me to make sense of a lot of code in my project 🎉

Im in love of these kind of presentations of concept. I watched a lot of videos like these(every religion explained, every ideology) and its actually a good way.

Damn, its my 3rd day of learning React and you already taught me a lot.!! What a great way to explain, so much easy explanation and best visuals

Amazing video. Got me hooked. I think you should do this for other technologies as well, like Node & Express and Databases

Your tutorial is so insightful Sir. Thank you so much.

This is the best React video I have seen on the internet since I've first learned React.

Damn this is the most clear explanation of React. Everything is on point.

Thank you so much for such a great video, you have explained almost every needed concept; keep it up bro

I also took a look at your course and it too looks excellent!

Your videos are awesome ❤❤. Can you make more of these types of videos for other programming languages? I’m sure nobody has done what you’re doing. It’s remarkable 🎉🎉

Really great explanation ❤

watched this 1 time.. will comeback for sure

wow awesome explantion of all react concepts in a simpler way . Please also make a video on next JS also

Cool stuff brother! 💪🔥

very well summarized!

This guy is underrated. Thank you man

I am happy about the memes used throughout the whole video more than the fact that this video helped me learn concepts i didn't get previously

hope you could do something like this in data structures and algorithms.

like the teaching style keep it UP!!

I very rarely leave comments on KZread but it’s the best video about basics of React. Thank you!

Beautifully Discribed.

Really happy to have you back , looking forward for more content , love from india

Loved this ❤

@@heyyounotyouyou3761the key is meant to tell react reconciliation when an item in a list changes so it doesn’t need to do rerenders on items which haven’t changed. If your list changes order then the index is not reliable as a key.

@@heyyounotyouyou3761 React uses the "key" prop under the hood to know which elements were kept the same and which ones were added/removed in the next render when a mutation of the list happens. The problem with using index as the "key" is as follows: imagine we have a list containing the strings ["a", "b", "c," "d"], iterating over the list and giving them the index as the "key" prop would generate the following - lets say we remove the string "b" from the list, the map function would generate , as you can see, the elements with the text "c" and "d" now have different keys, so, instead of react knowing the element with the string "b" was deleted, it thinks the element with the string "b" was changed to have "c", the element with string "c" was changed to have "d" and that the "d" element was deleted. This makes react re-render 3 components unecessarily instead of just 1. This might not be a big deal for short lists, but for big ones, it's a huge performance loss. Hope this helps. And if you still don't understand, feel free to ask questions 😄

Never use indexes as keys, it can lead to behaviours that are very hard to debug, especially if the underlying list is modified.

You should never iterate over an iterable that will be modified. You must create a copy of the iterable for the loop and modify the original iterable separately.

On 5:42 the function handle click should have the setLikes method instead of setClicks

This video is awesome 👍 By the way i guess there is a small typo at 5:48 Setlike(likes+1)

Aula mto boa professor! Imagino q o fato de enterrarem os antepassados na própria casa pode ter relação com oq vc falou no vídeo da Cidade Antiga, que a região era puramente familiar. Outra coisa interessante que pode ser pauta de um vídeo futuro é a relação entre a monogâmia, o patriarcado e a revolução agrícola. Até onde eu me lembro, sociedades pré agricultura não tinham muito claro esses dois conceitos sedimentados.
