• 需求：编写MySetInterval函数，实现每隔一秒控制台输出 0 1 2 3
• 

	  async function mySetIntervalue(count = 0) {
	    let data = await new Promise((resolve) => {
	      setTimeout(() => {
	        resolve(count);
	      }, 1000);
	    });
	    console.log(data);
	    count < 3 ? mySetIntervalue(++count) : '';
	  }
  	  mySetIntervalue();
