Testing

export function setupCounter(element: HTMLButtonElement) {
 let counter = 0;
 console.log(new Error("test").stack);
 const setCounter = (count: number) => {
 counter = count;
 element.innerHTML = `count is ${counter}`;
 };
 element.addEventListener("click", () => setCounter(counter + 1));
 setCounter(0);
}
