如何在默认不选中复选框的情况下在typescript中构建函数？

<input type="checkbox" id="myCheckbox">
<label for="myCheckbox">复选框</label>

const myCheckbox = document.getElementById("myCheckbox") as HTMLInputElement;

function myFunction(checked: boolean): void {
  if (checked) {
    console.log("复选框被选中");
  } else {
    console.log("复选框未被选中");
  }
}

myCheckbox.addEventListener("change", () => {
  myFunction(myCheckbox.checked);
});
