Using ngIf?

Question

Angular

Then I came across an article that said that it is better to avoid using ng-if and ngIf in angular 1 and 2. It became interesting because for all the time I have been working with angular, which is about 1.5-2 years, there have never been problems with these directives . What do you think about this, is it worth using them or not?

Answer 1

And the article itself does not say why "it is better to avoid using ng-if and ngIf"?
