Does angular2 have ngCloak

Question

AngularJS 1.x has ngCloak directive, which is used to prevent the Angular html template from being briefly displayed by the browser in its raw (uncompiled) form.

Does Angular 2 have any such directive or functionality to prevent such raw(uncompiled) form display.

Answer 1

Angular2 desn' have ngCloak,

instead you can use ?. operator (use it with object).

{{user?.name}} 

AND/OR

you can use *ngIf (as of now)

<div *ngIf="name"> {{name}}</div> 

Answer 2

There are two types of compilations in Angular2 ,Just-in-Time(JiT) and Ahead-of-Time(AoT). Just-in-Time is the default compilation.

JiT compilation incurs a runtime performance penalty.Views take longer to render because of the in-browser compilation step. The application is bigger because it includes the Angular compiler and a lot of library code that the application won't actually need. Bigger apps take longer to transmit and are slower to load.

With AoT, the browser downloads a pre-compiled version of the application. The browser loads executable code so it can render the application immediately, without waiting to compile the app first.

If we go with Ahead-of-Time compilation instead of Just-in-Time compilation, we can prevent such raw(uncompiled) form of display.
