Angular 2 declaring an array of objects

Question

I have the following expression:

public mySentences:Array = [
    {id: 1, text: \'Sentence 1\'},
    {id: 2, text: \'Sentence 2\'},
    {id: 3,         


        

Answer 1

Datatype: array_name:datatype[]=[]; Example string: users:string[]=[];

For array of objects:

Objecttype: object_name:objecttype[]=[{}]; Example user: Users:user[]=[{}];

And if in some cases it's coming undefined in binding, make sure to initialize it on Oninit().
