Accepted answer
you're trying to use the getinitialstate
lifecycle method inside your react component created using es6
classes, which isn't supported. you should change to a constructor and setting your initial state inside of it.
class menuexample extends component {
// eslint-disable-next-line
constructor(props) {
super(props);
this.state = { focused: 0 };
}
...
it is explained here.
