如何在JavaScript中为自定义对象创建方法？

const myObject = {
  property1: "value1",
  method1: function() {
    console.log("This is method1");
  }
};

myObject.method1(); // 输出 "This is method1"

function MyObject() {
  this.property1 = "value1";
  this.method1 = function() {
    console.log("This is method1");
  };
}

const myObject = new MyObject();
myObject.method1(); // 输出 "This is method1"

function MyObject() {
  this.property1 = "value1";
}

MyObject.prototype.method1 = function() {
  console.log("This is method1");
};

const myObject = new MyObject();
myObject.method1(); // 输出 "This is method1"

class MyObject {
  constructor() {
    this.property1 = "value1";
  }

  method1() {
    console.log("This is method1");
  }
}

const myObject = new MyObject();
myObject.method1(); // 输出 "This is method1"
