Why useState??? and Some important basic things of React useState Hook,I have noticed....

-----------------------------------------------

• "useState" related to taking/getting a state and updatingState function for any updating state. Ex: const [count,setCount] = useState(0);
• We can use any "premetive data" or "array object" for useState argument (argument not parameter)
• "premetive data" is more preferable for beginner
• "array object" is difficult to implement and understand the code for a beginner.
• Implemented argument in useState function," "premetive data" or "array object" " return two this such an state and state updating function. Ex: const [count,setCount] = useState(0); //Here , "count" is a state and "setCount" is a state updating function. "0" is a premetive data.

Best of Luck all of you.....

const [fooObject, setFooObject] = useState({});

useState return two elements array give free to declare state and action ( value / setter ) names, in one step;

Thanks,
I have told here, " such an state and state updating function. " .
I think updating means not only increment or decrement a state but also new value setting in a state.
