重新审视在ECMAScript 5之后扩展原生原型

Object.defineProperty(Array.prototype, 'myMethod', {
  value: function() {
    // 方法的实现
  },
  writable: true,
  configurable: true,
  enumerable: false
});

Object.defineProperties(String.prototype, {
  myProperty1: {
    value: 'myProperty1Value',
    writable: true,
    configurable: true,
    enumerable: false
  },
  myProperty2: {
    value: 'myProperty2Value',
    writable: true,
    configurable: true,
    enumerable: false
  }
});

Object.assign(Date.prototype, {
  myMethod: function() {
    // 方法的实现
  }
});
