setTimeout(()=>{
    t1();
},1000)

setTimeout(()=>{
    t2();
},2000)

// In a function that needs to continue execution after T1 and T2 have completed

1. const group = _Task(taskGroupName:string):{wait ()=> Promise<any>, add(childTaskName)=>resolve}

   Create a task group that can add countless subtasks.

   创建一个任务组，这个任务组可以添加无数的子任务。

2. group.wait():promise

   This returns the Promise.all of the missions.

   这个返回全部任务的Promise.all。

3. group.add(childTaskName:string):resolve

   Add a subtask that returns the resolve used to complete the task.

   添加一个子任务，该任务会返回用于完成该任务的resolve。

4. const val:any[] = await group.wait()

   Val will retrieve all the values of resolve and return them as an array.

   val会获取全部resolve的value，作为数组返回。
