Manipulating hashes in an array using AngularJS

I currently have an array containing the following elements:

$scope.users = [{"id": "1", "name": "Jai Rajput"}, {"id":"2", "name": "Nakul Sharma"}, {"id": "3", "Name": "Lovey Rajput"}]

My goal now is to efficiently update and delete items in this particular Array.

Answer №1

Both tasks can be accomplished using the Array#find method.

let $data = {};
$data.students = [{"id": "1", "name": "John Doe"}, {"id":"2", "name": "Jane Smith"}, {"id": "3", "Name": "Alice Johnson"}];

$data.students.find(student => student.id == 1).name = "Johnny Doe";
$data.students.splice($data.students.indexOf($data.students.find(student => student.id == 3)), 1);

console.log($data.students);
