Does using array.push(val) to push values into an array in AngularJS result in creating a deep copy?

Is a deep copy of the pushed value created inside the array when using array.push() to add values at the end in AngularJS?

Answer №1

When you add an object to an array, you are simply adding a reference to the original object, not a copy of the value.

var obj = { key: "value" }
var arr = [];
arr.push(obj);

obj === arr[0];
// This will return true

Answer №2

Indeed, achieving a deep copy is possible using angular.copy method. Allow me to illustrate.

let information = [{'name':'abc'}, {'name':'xyz'}];
let copiedData = angular.copy(information);

Answer №3

When working with Javascript, it's important to keep in mind that objects are typically passed by reference unless you explicitly create a copy.
