How can I force component to re-render with hooks in React?

Question

Considering below hooks example

   import { useState } from \'react\';

   function Example() {
       const [count, setCount] = useState(0);

       return         


        

Answer 1

This will render depending components 3 times (arrays with equal elements aren't equal):

const [msg, setMsg] = useState([""])

setMsg(["test"])
setMsg(["test"])
setMsg(["test"])
