The example here would cause a TypeError: Assignment to constant variable.

Can you tell me what the actual issue in this code? because I show there is no issue. ( Tell me how you get this issue. )

I found that code on the page and this code is written for the what kind of mistake cannot do in react state (Don’t mutate State ).

const [foo, bar] = [1, 2];
foo = foo + 1;
// Uncaught TypeError: Assignment to constant variable.

const Counter =()=> { const [count, setCount] = useState(0);

const handleClick =()=> setCount((prev)=>prev+1)

}
