I have an issue:

    //this console log displays correct value
    console.log('localstorage', localStorage.getItem('subMenu'));
    
    setSubMenu(
      JSON.parse(localStorage.getItem('subMenu') || JSON.stringify(subMenu))
    );
    /*
    this one displays JSON.stringify(subMenu) value, when 
    localStorage.getItem('subMenu') is defined 
    */
    console.log('subMenu', subMenu);

I have no idea what's happening. there is value in localstorage (checked with console logs), but somehow JSON.parse is reading second value.
