*****useState******

 USE STATE IS A REACT HOOK THAT LET'S YOU ADD A STATE VARIABLE TO YOUR COMPONENTS.

WHENEVER, WE WANT CHANGES IN UI, BASED ON SOME EVENTS WE USE STATE VARIABLES.

const [state, setState]= useState(initial state)

USE STATE RETURNS AN ARRAY  WITH EXACTLY TWO VALUES.

THE CURRENT STATE

DURING THE FIRST RENDER, IT WILL MATCH THE INITIAL STATE YOU HAVE PASSED

THE SET FUNCTION

LET'S YOU UPDATE THE STATE TO A DIFFERENT VALUE.

THE ARRAY RETURNED BY THE USESTATE METHOD IS DE-CONSTRUCTED.

let [stateVariable,setStateVariable]=useState(0)

THE setStateVariable  ENABLES YOU TO UPDATE THE STATE.

import { useState } from "react";

export default function Counter() {
  let [count, setCount] = useState(0);

  let incCount = () => {
    setCount(count + 1);
  };
  return (
    <>
      <h3>Count={count}</h3>
      <button onClick={incCount}>increase count</button>
    </>
  );
}

[] - EMPTY , MEANS THAT SIDE EFFECT IS PERFORMED ONLY WHEN THE PAGE IS RENDERED ( NOT RE-RENDERED). ( IN THE BEGINNIG)  EX- WE CREATE TWO STATE VARIABLES, COUNTX AND COUNT Y , HERE WE ONLY ADD SIDE EFFECTS TO COUNT X. import { useEffect , useState } from "react" ; export default function Counter () {   let [ countx , setCountx ] = useState ( 0 );   let [ county , setCounty ] = useState ( 0 );   let incx = () => {     setCountx (( currCount ) => currCount + 1 );   };   let incy = () => {     setCounty (( currCount ) => currCount + 1 );   };   useEffect ( function PrintSomething () {     console . log ( "this is a side effect" );   },[ co...
