在JavaScript中，可以从类外部访问用TypeScript编写的具有受保护/私有字段的类吗？

class MyClass {
  protected protectedField: string;
  private privateField: string;

  constructor() {
    this.protectedField = 'protected value';
    this.privateField = 'private value';
  }

  getProtectedField(): string {
    return this.protectedField;
  }

  setProtectedField(value: string): void {
    this.protectedField = value;
  }

  getPrivateField(): string {
    return this.privateField;
  }

  setPrivateField(value: string): void {
    this.privateField = value;
  }
}

const myObject = new MyClass();
console.log(myObject.getProtectedField()); // 输出：protected value
console.log(myObject.getPrivateField()); // 输出：private value

myObject.setProtectedField('new protected value');
myObject.setPrivateField('new private value');

console.log(myObject.getProtectedField()); // 输出：new protected value
console.log(myObject.getPrivateField()); // 输出：new private value
