如何在JavaScript中传递引用？

function modifyObject(obj) {
  obj.property = "new value";
}

var myObject = { property: "old value" };
modifyObject(myObject);
console.log(myObject.property); // 输出 "new value"

function modifyArray(arr) {
  arr[0] = "new value";
}

var myArray = ["old value"];
modifyArray(myArray);
console.log(myArray[0]); // 输出 "new value"

function modifyFunction(func) {
  func();
}

function myFunction() {
  console.log("Hello, World!");
}

modifyFunction(myFunction); // 输出 "Hello, World!"
