Differences Between Angular And AngularJS
In this article, we will learn about AngularJS and Angular as well as the key differences between the two.
AngularJS: AngularJs is an open-source front-end framework written in Javascript that is mostly used to create single-page web applications (SPAs). It is a framework that is always evolving and providing better ways to construct online apps. The static HTML is replaced by dynamic HTML. Its capabilities, like as dynamic binding and dependency injection, obviate the need for us to create code. Because AngularJs is continually evolving, we offer multiple versions, with the most recent stable version being 1.7.7. It's also worth noting that Angular is not the same as AngularJs. It is a free and open-source project that anyone can use and modify. Directives expand HTML attributes, and data is connected with HTML.
Angular: It is a popular open-source Typescript framework for constructing web apps that was created by Google. For efficiently showing and manipulating data, front-end developers employ frameworks like Angular or React. In comparison to the prior version of Angular, the updated version is substantially more efficient, with the main functionality being separated to different modules. As a result, it becomes considerably faster and smoother than before. We may install the essential packages that ease construction and turn complex-structured code into a modular form that is easy to maintain using the newly integrated angular CLI.
Although, there are several key differences between AngularJS and Angular, which can be classified as follows:
Support for ES6:
Angular is written entirely in Typescript and adheres to the ECMAScript 6 standard. This means it supports ES6 Modules, Class Frameworks, and other features.
Components are new controllers:
We had Controllers in AngularJS. Angular Components replace Angular Controllers in Angular. In AngularJS, the controllers and views are defined as follows:
//View
<body ng-controller="’appController’">
<h1>vm.message<h1>
</h1></h1></body>
//Controller angular.module(‘app’).controller(‘appController’,appcontroller) {
message=’Hello Angular’;
}
import { Component } from '@angular/core';
@Component({
selector: 'app',
template: '<h1>{{message}} </h1>'
})
export class AppComponent {
message: string=’Hello Angular’;
}
Directives:
<ul>
<li ng-repeat =customer in vm.customers>
{{customer.name}}
</li>
</ul>
<div ng-if=”vm.isVIP”> <h3> VIP Customer </h3> </div>
<ul>
<li *ngFor =#customer of customers>
{{customer.name}}
</li>
</ul>
<div *ngIf=”vm.isVIP”>
<h3> VIP Customer </h3>
</div>
@Directive({
selector: '[MyDirective]'
})
class MyDirective { }
Data Bindings:
Interpolation:
//AngularJS
<h3> {{vm.customer.Name}}</h3>
//Angular
<h3> {{customer.Name}}</h3>
One way Binding:
//AngularJS
<h3> ng-bind=vm.customer.name></h3>
//Angular
<h3 [innerText]=”customer.name” ></h3>
Any property of an HTML element can be bound by Angular.
Event Binding:
Two- way binding:
//AngularJS
<input ng-model=”vm.customer.name”>
//Angular
<input [(ng-model)]=”customer.name”>
$scopes are out:
Filters are renamed to Pipes:
<td>{{vn.customer.name | uppercase}}</td>
<td>{{customer.name | uppercase}}</td>
Platform-specific Bootstrap:
<body ng-app=’app’> </html>
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import {AppModule } from './app.module'; platformBrowserDynamic().bootstrapModule(AppModule);
