How to add new elements to an array without overwriting the first one?

Question

I'm trying to add new elements to an Array but it keeps overwriting it the first element, i'm not sure if i'm doing it correctly, but this is my code:

//name and age contains value from a NgModel 
this.data = [
    { "name": this.name, "age": this.age },
];

//Adds them to a new array 
this.nArray = [];
this.nArray.push(this.data);

Answer 1

Use concat when you want to merge two arrays.

const nArray = [];
const arr = nArray.concat(this.data);

You can now use the new merged array for your purpose
