无法将默认值设置为 useState

Question

I am new in React and do not understand why this lines doesn't work:

const { showProjects, setShowProjects } = useState(true);
  console.log(showProjects);

Currently it returns undefined when I am trying to make it return true for example.

Answer 1

const [showProjects, setShowProjects] = useState(true);
  console.log(showProjects);

Answer 2

You have to define hooks const this way:

const [ showProjects, setShowProjects ] = useState(true);

See useState docs
