我有以下模板：
<div *ngFor="let item of myArray | customPipe1 | customPipe2; let l = length">
Here is the length of my ngFor : {{l}}
</div>
不幸的是,ngFor中不存在长度.我如何解决这个问题,以便在我的ngFor中提供长度？
<div *ngFor="let item of myArray | customPipe1 | customPipe2 as result">
Here is the length of my ngFor : {{result.length}}
</div>
