如何在Typescript中创建一个可以使用对象或常规参数构造函数进行初始化的类？

class Example {
  private prop1: string;
  private prop2: number;

  constructor(obj: { prop1: string, prop2: number });
  constructor(prop1: string, prop2: number);
  constructor(arg1: any, arg2?: number) {
    if (typeof arg1 === 'object') {
      this.prop1 = arg1.prop1;
      this.prop2 = arg1.prop2;
    } else {
      this.prop1 = arg1;
      this.prop2 = arg2;
    }
  }
}

const obj = { prop1: 'value1', prop2: 2 };

const instance1 = new Example(obj);
console.log(instance1); // Example { prop1: 'value1', prop2: 2 }

const instance2 = new Example('value2', 3);
console.log(instance2); // Example { prop1: 'value2', prop2: 3 }
