Angular - Creating a model with Array property

Question

I'm trying to understand how to create a model that includes an array. I am trying to do something like this but I'm getting an error :

ERRROR

Argument of type 'elset' is not assignable to parameter of type 'elset[]'.

MODEL

export class elset{
    constructor(
        public name: string,
        public title: string
    ){}
}
export class pageModel{
    constructor(
        public type: string,
        public set: elset[]
    ){}
}

SERVICE

@Injectable()
export class customService {
    constructor ( ){}

    types = [
        new pageModel('home', 
                     new elset('something','somethingelse')
                     )
    ];
}

You defined the second parameter as an array of elset instances here:

export class pageModel{
    constructor(
        public type: string,
        public set: elset[]  <--------------------
    ){}
}

So you need to pass an array:

new pageModel('home', [new elset('something','somethingelse')])

Yep, Thank you. @Maximus, if it is an object then it would be public set: elset{} ? and then I could do new pageModel('home', new elset('something','somethingelse')

simply public set: elset, yes, then you'd be able to do the way you did it
