What i also learned today from this video are as written below:
1. State=condition of any component for eg. textarea component might be empty sometime, sometimes it has letters .
2. Hooks= A method which helps us to use features of classes in function based component this is because developer like us prefer to use function over classes.
3. Hooks has this part ----> const [count, setCount)=useState("Hello Universe");
Here in above hook the value of count is Hello Universe . count is array variable so that we just can't update or change its value like normal variable.
But we can update or change its value using setCount() method. i.e. setCount("Hey You"); this implies the value of count is updated to Hey You.

What is inside this mini project and what i do?
---> Project provides mini textarea and 2/3 buttons like UpperCase, LowerCase, No. of letters. we change the text value according to the buttons instruction using state and event.
Its more simple as we use onClick={ClickFunction) and we define its functionality as well.

Note : Advantages of hooks and this stuff, whenever you click Uppercase button page does not reload. Which enhances its capability. IMP*

Harry brother, you are doing a great job, I have seen this kind of effort to make people understand. I visited multiple platforms to learn react but believe me that was just a waste of time for me. It is for the first time that my all concepts for props and state are cleared! Love from

I was a big fan of harry n now of react.js too 🔥🔥🔥

[adarshanand]

I really find the way you explained the concept in such an easy and efficient way. Most of the tutorials uses big and advance words to show off but this one hit different. Thanks for the concept man 🔥

[bijayghosh]

Hello Harry Bhaiya. I am a slow learner, so have to watch your video atleast 5 times to understand the concepts in detail and also have to read the react documentation line by line. But at the end I must say, till lecture 7(my current watching) everything is crystal clear .

thank you Bhaiya
