I dont usually coment on anyone's tutorial video ,But In this case , You are a great tutor thanks a lot I understood all being only 17 year old Still I understood all the 10 lifecycle methods ,Thanks a lot
Just a note, if parent renders.. all child components will not go through all constructor, willmount and all.. it will only call child's render at the time of parent re-rendering..

I want to know that when I try to setstate of component's variable without using lifecycle hooks but with custom function why does it goes into infinite loop and call same function again and again. I triggered that function with onclick event so why is it rerendering without clicking again
Hi Pradhumn! Would you be interested in job opportunities in web development? We are a web development company looking for developers. Please let me know if interested!
If you are rendering on serverside the only thing server can do is componentWillMount because component is actually gets mounted on client so componentDidMount and other lifecycle hooks runs on clientside.

Thanks very much for the video. I have a question regarding the binding of “this” at @13:19 “onClick=this.changeState.bind(this)” Can you please explain what the 2 “this” refer to? Cheers
In this case it may work, but you can get some nasty and hard to find bugs if you don't bind your component to your constructor. You can also use ES6 fat arrow function as well to preserve 'this'.
Eleazar, that is a good question. you can build a page where you load some data via api call, also have another field that makes change in the state by changing a field . This should be good to pretty much test all the hooks.

I am calling a fetch ajax call in DidMount, where I get the json data which I set it in setState and in my redux store. Later when I reload/refresh the page the data from the state is gone. I have been trying to resolve this for a long long time but all in vain. :(
For the workaround I am storing data in my localstorage and assign it to state in DidMount and ajax call I moved to WIllMount. But that is wrong, it should be done by redux. I have also added persistData in redux store. But the data in it is updated after few render calls have gone passed. And then it gets the data. I wonder why it issues multiple render calls even before fetching the data from ajax in WillMount

@@suhasnayak4704 Okay. Thanks for your response!
I don't understand one thing, when you defined componentWillUnmount in App.js file why is it showing child componentWillUnmount on console.log
Second thing I want to ask is that Is it good coding if we call lifecycle hooks in another function?
basically, when component is unmounting it first unmount it children. that is why child components also shows componentWillUnmount
I want to know that when I try to setstate of component's variable without using lifecycle hooks but with custom function why does it goes into infinite loop and call same function again and again. I triggered that function with onclick event so why is it rerendering without clicking again
Hi Pradhumn! Would you be interested in job opportunities in web development? We are a web development company looking for developers. Please let me know if interested!
Awesome! Can I know what is that you said about 'server rendering' in componentWillMount lifecycle method?
If you are rendering on serverside the only thing server can do is componentWillMount because component is actually gets mounted on client so componentDidMount and other lifecycle hooks runs on clientside.
the explanation is nice.

I have a question regarding the binding of “this” at @13:19 “onClick=this.changeState.bind(this)”
Can you please explain what the 2 “this” refer to?
Cheers
'this' here means your component.
But is it necessary to use the bind method? It works fines without as well
In this case it may work, but you can get some nasty and hard to find bugs if you don't bind your component to your constructor. You can also use ES6 fat arrow function as well to preserve 'this'.
i want to build a small project wich I can use all this hooks, what is the best small projects to make?
Eleazar, that is a good question. you can build a page where you load some data via api call, also have another field that makes change in the state by changing a field . This should be good to pretty much test all the hooks.
very nice explanation
