ReactJS Tutorial - 11 - setState

This whole series is perhaps the best React series that I’ve seen. I like how you’re showing one way, and then another way.. so it is apparent how each change effects whatever you’re doing. That’s very effective for me. Thank you!

Vishwaas you're an amazing teacher. You know how to structure a course and deliver content very well without causing any confusion in the learner's mind. I'm currently on this video and I don't intend to leave my room until I watch the entire series. Thank You so much.

Hi guys, I will leave this here, just in case it could help someone: In the last example, he wrapped in parentheses everything after the "=>" ...I searched for that and found the following: "Using arrow functions with object literals: If you are returning an object literal, it needs to be wrapped in parentheses. This forces the interpreter to evaluate what is inside the parentheses, and the object literal is returned
( example: x => ({ y: x }) )"

0:25 extension ES7 React of Visual Sudio code
4:59 why we should never modify the state directly: the state.count is changed only in console, but not in screen (react does not re-render the component)
9:11: what if we want to execute some code after the state has been changed: use call back function.
11:00 pass afunction to the setState
13:54: summary about setState

The quality of these videos are superb, just look at the like to dislike ratio

The best react series anywhere, really. If you read the docs in conjunction to each of these videos, you learn very swiftly. These examples demonstrate the core react/JS fundamentals. Thus is great!

Hello Vishwas... Loving this series so far! I love the way you teach and leave no stones unturned while explaining a concept... Thank You V!

It's 2024 and we do not use Classes as much anymore. Focus on functional components and hooks, as they are the future and present of React. However, having a basic understanding of class components is still valuable for working with older codebases and gaining a well-rounded knowledge of React.

I like how you create various scenarios to demonstrate important react concepts.

One of the best React lessons in Youtube! Clear and easy to understand!

[Seaspray]

You are a good instructor. A lot of these tutorials give the imporession they are just an experienced programmer showing off. You break down the steps to the level of a beginner React student who doesn't tune into the gobblede goop technical explanations that would make sense to an advanced programmer looking at a single function. Thank you for making this course.

[SumanDas-fxvu]

I think, probably you are the best teacher on youTube for react. The way you explain each and every concept is really amazing.

[amanpreetsinghbawa]

These concepts are really gem & very well presented in this video. I have practically seen this in real time projects where devs tend to perform these misses due to inadequate understanding of these internals

[ronaldmelendez]

prevState is defined by the setState function. So basically if you add a function to the setState method the argument for the function enter in the setState method is automatically the previous state. It's not predefined by the programmer, it is defined by the setState function.

This series is a true gem! I've been watching it in January 2023, even after 4 years, it still holds up. I commend the effort and dedication you put into making these videos. Keep up the fantastic work!

Seriously the best explanation available on this subject, even compared to paid courses. Thank you so much!
