How to concat string in Ionic 4 with the template?

Issue

I need to contact the name and surname in my Ionic 4 Full Starter kit template:

 <app-text-shell [data]="customer?.surname + customer?.name"></app-text-shell>

Unfortunately there is not the space between them; how Can I do? If I create a function in customer link getNameAndSurname() there is a message error.

Solution

Simply Pass this way

<app-text-shell [data]="customer?.surname +" "+ customer?.name"></app-text-shell>

add space

+" "+

or

customer = { surname: "weerasinghe", name: "chanaka" };

.html

<app-text-shell [data]="customer"></app-text-shell>

Access data

 this.data.surname
