call a method inside a ngFor in my html (angular6)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;

I'm new to stackOverflow, couldn't find an answer to my question.
I'm trying to use an ngFor inside an ngFor.
Is it possible to call a method inside an *ngFor:
something like this :
<div *ngFor="let nbStar of myMethod(skill.level)">
where myMethod is using data from my first ngFor as parameter to generate an array of numbers.
my code:
<div *ngFor="let skill of skills">
<div class="picture">
<img src="skill.skillPicture"/>
</div>
<div class="title-skill">
<h3> uppercase </h3>
Niveau:
<div *ngFor="let nbStar of generateStarsArray(skill.level)">
<i class="fas fa-star"></i>
</div>
</div>
</div>
Thanks a lot for any clues.

Yes you could use it. but make sure your method returns always an array.
For the following template
<div *ngFor="let skill of skills">
<div class="picture">
<img src="skill.skillPicture"/>
</div>
<div class="title-skill">
<h3> uppercase </h3>
Niveau:
<div *ngFor="let nbStar of generateStarsArray(skill.level)">
<i class="fas fa-star"></i>
</div>
</div>
</div>
in component.ts method generateStarsArray should be something like below
public generateStarsArray(level): Array<any>
let stars = ;
//---> some logic
return stars;
