Angular forEach all object from class

Question

is there any way in angular 2 (v. 2.4.0) to make for loop, or forEach loop taking every objects from class? I mean

export interface RegistrationDataInterface {
first_name: string;
    surname: string;
    used_name: string;
    email: string;
}
export class Smth{
registrationSharingData: RegistrationDataInterface;
 checkOut(){
forEach(item from this.registrationSharingData)
{
    if(item!="null")
    {//dosmth}
}}}

I dont want to make 20 ifs, thanks :)

You can do this,

for (let item of this.registrationSharingData){

}

since you want to check inside the Object, you don't need a loop,

checkOut(){
   You can just access the properties like this.registrationSharingData.whateverfield
}

Type 'RegistrationDataInterface' is not an array type or a string type. – Jędrek Markowski Jun 29 '17 at 10:06
is not it an array? – Sajeetharan Jun 29 '17 at 10:07

Nope, sorry I wasn't clear I need to pick all the items (first_name, surname, etc) from just 1 class, not from array of classes + I edited my example code – Jędrek Markowski Jun 29 '17 at 10:10
I know that I can access the properties like that :) I just wanted to check my every field using loop or smth, because I dont want to write ifs for every of them, it can be impossible as well. – Jędrek Markowski Jun 29 '17 at 10:15
you cannot loop over object – Sajeetharan Jun 29 '17 at 10:17

You can loop through object properties using the `for (var key in object)` loop. If this fits you I'll post an answer. – Ploppy Jun 29 '17 at 11:16
