Why & When You Should Use ngIf else

Until a while ago, I still couldn’t convince myself when I should use Angular If Else Directives.

This is due to most of the time, writing 2 *ngIf (refer the below code) was enough to support my use case.

The ngIf else way

Why ngIf else?

After several rounds of thinking, I finally able to discover the reasons that are enough to persuade myself to use ngIf else.

• Firstly, using ngIf else allows you to reduce one if validation. You don't have to write two *ngIf validation.
• Secondly, you can reuse the loadingView declared above code. For e.g, you can reuse the loadingView when you're retrieving data from server or submitting data to server.
