Ember.js is one of the most widely used front-end application frameworks. It is made to speed up development and increase productivity. Currently, it is utilized by a large number of websites, including Square, Discourse, Groupon, Linked In, Live Nation, Twitch, and Chipotle.

import Ember from 'ember';
let Student = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
init() {
alert(`${this.get('firstName')} is Listed`);
},
fullName: Ember.computed('firstName', 'lastName',
function () {
return `${this.firstName} ${this.lastName}`;
}),

export default class PartyRoute extends Route {
students = [{
Name: 'Balit',

setupController(controller, model) {
super.setupController(controller, model);
controller.set('students', this.students);
controller.set('temp', this.temp);
controller.set('item1', this.item1);
controller.set('item2', this.item2);
controller.set('item3', this.item3);
}
}

Changed: Ember.observer('fullName', function () {
console.log(`fullName changed to: ${this.fullName}`);
}),
});
export default class Array2Controller extends Controller {
@action
print(data1, data2, data3) {
let temp = Student.create({
