What happens when you destructure a class method and a class-field arrow off an instance and call them?

class Counter {
  count = 0;
  increment() {
    return ++this.count;
  }
  incrementArrow = () => ++this.count;
}
 
const counter = new Counter();
const { increment, incrementArrow } = counter;
 
console.log(incrementArrow());
console.log(incrementArrow());
console.log(counter.increment());
console.log(increment());
console.log("done");
