unable to access content of array by index when created using array.push

Question

Whenever i create array at initialization it works fine. i can access it using Array[index]. but whenever i create an empty array array = [] , and then push array data using push , i cannot access it using Array[index].

testAdd: Address[]= [{add: "D/102", loc: 'thane'},{add: "Room No, 106", loc: 'Mumbai'}];
Add : Address[] = [];
this.Add.push({add:"102,ajaynagar", loc 'andheri'});
console.log(this.testAdd[0])  //results:-  {add: "D/102", loc: 'thane'}
console.log(this.Add[0])    // results:- undefined

i want to fill up the array using push command from the data coming from database. it fills up correctly but retrieval shows undefined

Is Add : Address[] = []; still reference to this.Add or it's variable defined just there? — Buczkowski

':' expected. Change this.Add.push({add:"102,ajaynagar", loc: 'andheri'}); — Ininiv

You missed an ":" in your push method:

this.Add.push({add:"102,ajaynagar", loc: "andheri"});

Correct your code, you cant assign value like this, you missed ':'.

testAdd: Address[]= [{add: "D/102", loc: 'thane'},{add: "Room No, 106", loc: 'Mumbai'}];
Add : Address[] = [];
this.Add.push({add:"102,ajaynagar", loc: 'andheri'});
console.log(this.testAdd[0])  //results:-  {add: "D/102", loc: 'thane'}
console.log(this.Add[0])
