The following piece of code screams due to this being undefined.

function myFunc(f) {
  console.log(f());
}

class Test {
  potato = "potato";

  test() {
    return this.potato;
  }
}

const t = new Test();
myFunc(t.test);

How can I overcome this issue?

Use `myFunc(t.test.bind(t))` – Barmar Aug 18 '23 at 19:34
