Is a deep copy of the pushed value created inside the array when using array.push() to add values at the end in AngularJS?
Is a deep copy of the pushed value created inside the array when using array.push() to add values at the end in AngularJS?
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
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);
When working with Javascript, it's important to keep in mind that objects are typically passed by reference unless you explicitly create a copy.
