Angular ngFor lifecycle

Question

I\'m using *ngFor to iterate some data like this:

 {{d}} 

Everything is fine

Answer 1

This issue has no relation with *ngFor, It's the normal behavior of the expression inside the interpolation ({{ }}). It is called by angular intentionally multiple times to check if the expression has changed. Interpolation is meant for fetching (printing) expressions and not recomended for calling methods. It will fire unnecessarily.

Issue is with the method inside interploation not *ngFor
