Add a key/value to a typescript object

Question

I have an array object that I want to add in position 0 a key and value in it.

I tried something like:

this.testeobj//meu objeto
this.testeobj[0].push({oi: 'teste});

Answer 1

Vc wants an array of objects

this.testeobj = [] //seu array de objetos
this.testeobj.push({oi: 'teste});

The push is a property only of the array, it will insert at the last position of your array the value passed which in your case is an object.

The example below passing the position is only when you want to put the value in the exact position of the array

this.testeobj[0] = {oi: 'teste};

I hope I’ve helped
