Components of Angular vs AngularJS
Components of Angular
Angular is made up of several core components like templates, data bindings, services, directives, and so on. Some of these components can be downloaded while others are included with the framework.
Angular is a component-based web application framework and it’s maintained by Google.
Angular has many components that are the most commonly used:
Angular Component – represents a single component in the app
Component – represent a component that can be reused across an application / usually metadata about the component such as dependencies, lifecycle hooks, and directives
Interface – define an interface of a class or object
Types – define types of data (data to track) and functions (to manipulate) over data
Services – defines services that can be shared across an application.
Templates – A template is just a raw representation of an html tree. It provides us with initial DOM structure of what the component will look like when it’s rendered in the browser.
Data bindings – In Angular, we can bind the input controller of our app with the output component using two-way binding. For example, let’s say we have an input controller named “name” and an output component called “nameLabel”. When someone inputs string “John Smith” on our input controller, then name label will display “John Smith”. Data bindings are crucial in Angular as they allow us to help us share properties between UI components
Directives – The Directives in Angular are used for a lot of purposes, including Angular Material and other libraries like Ionic. There are different directives that can be used for different purposes. Angular directives are small, declarative components which can be used in the templates and declarations to define their behavior. The directives in Angular provide a rich functionality that is used by developers to create reusable code and reduce repetitive work.
Components of AngularJS
AngularJs is built on top of concepts such as data binding, dependency injection, services and directives. These help make the development process very simple in comparison to other frameworks like Backbone or Ember.
The components of AngularJS are as follows:
Directives – Define custom HTML elements on the page by using directive expressions
Controllers – Define custom HTML elements on the page by using controller expressions
Scopes – Manage data for a particular block of HTML on the page or application level and bind it with an expression to a controller or a directive
Services – Provided services to other components through dependency injection or an API endpoint
Architecture of Angular vs AngularJS
Angular vs AngularJS: Both Angular and AngularJS are open source frameworks for building web applications. They differ in their approach and philosophy about how to structure your app.
The main difference between these two frameworks is that the former has a strong dependency on components, data binding and powerful templates while the latter is more focused on style over structure. While both frameworks have been used for many years, it’s only recently that they’ve gained popularity due to the advances in front-end development practices.
Benefits of using Angular vs AngularJS
- Angular has a better structure than AngularJS and it contains many more features that make building applications with it easier. It also makes the development process faster and less expensive.
- The speed of developing, testing, and deploying an application in angular is way faster than AngularJS without sacrificing stability or security.
- Angular can be used by developers who are not familiar with the backend, because it uses TypeScript and HTML5 as its development language, which allows even non-tech savvy developers to easily get up and running with it.
- With Angular, you can build apps for desktops and mobile platforms; whereas with AngularJS, you can only build for browsers.
- There are many professional developers who are switching from using AngularJS to using Angular because of its rich ecosystem, more features in comparison to the previous version of the framework.
