React variable value isnt changing

i want to change a variable value and than log it to the console from another function.

But when i am logging it its always the same output and not the changed one.

Ive already tried it with the useState hook but that seems to be the same problem.

`

let text = 'Hello World';

const handleStart = () => {
    console.log(isStarted);
    text = 'loaded';
     //.....
    
  };

const handleClick = index => {
    console.log(text);
    if (!isStarted) return;
    //.....
  };
