Difference between AngularJS and Angular! How to Migrate?

19

Angular development has evolved exponentially in the past few years and with growth, many better versions also came into existence. You can rule the field of open-source Javascript after you Migrate from Angular JS to Angular and build a better user interface for your website or application. The different versions of Angular give you a chance to create a difference in a digital product.

Here, we are compiled some of the fact, essentials, comparison, and you will also learn how migration can make a difference in your product:

How is AngularJS different from Angular?

Well! There are so many differences between AngularJS and Angular. So, without any further ado, let’s proceed further and check how the AngularJS is different from the Angular version.

Architecture

  • The Angular JS structural concept is the Model-View-Controller design basis, that gives the central authority to express the application behavior and also them in managing the logic, data, and rules.
  • The advanced version of Angular changes the controllers and scope to the components and further changes into the directive and then transforms the components to the directives to help to hold the templates. This helps to manage the application and view logic.
  • The Angular Derivatives ngFor and ngif are improved and the developers can use if or else design syntax in the templates.

Language

AngularJS is written and compiled using the javaScript language whereas Angular uses the TypeScript Language for Microsoft and also supports the ECMAScript 6. This script further shares the dual advantages from the TypeScript and also supports the ES6 benefits like the lambdas and iterators. The latest version of Angular works fine with TypeScript and also supports features like object-oriented and iterators.

Expression Syntax

  • If you want to bind any image/property or event with AngularJS, you have to remember the accurate ng directive.
  • Angular uses “()” for the “Event Binding” and “[]” for the property binding.

Mobile Support

AngularJS does not have mobile support because it was designed considering a different perspective. Although, the Angular 2 and Angular 4 supports the different functionalities with mobile support. So, if you migrate from Angular Js to Angular 2 or 4, you can design the interactive website.

Routing

AngularJS version supports the $routeprovider, when () for the configured routing. The latest version of Angular uses the @RouterConfig {(…)}.

Performance

AngularJS version was typically designed for the designers and this version has a lot of improvement with time in the design and functionality, although, AngularJS does not suffice the need of the hour.

The subsequent version of Angular transmutes the entire performance, dependency injection, and speed.

Speed

With the latest advancement in technologies 2-way binding, the new advancements in the Angular JS have lessened the development time and efforts. Previously, the page loading used to take a lot of time during the page loading process at the client’s end.

Dependency Injection

The Angular’s complete mechanism is integrated with the unidirectional tree that supports the ‘Change Detection’. While working with Angular, you will get to know about the unique system known as Hierarchical Dependency Injection that it uses which encourages the better performance of the framework.

Being a product of Google, Angular has carved goodwill, and it is good to say that all the Angular versions are trustworthy and provides the all-time support from the Google Engineers team. But, all the Angular versions have distinctive benefits and quality. Let’s Check Out the pros and cons of AngularJS and Angular:

Pros of AngularJS

  • Developers can do unit testing at any time.
  • Developers can use declarative languages.
  • Well-Structured Front End development process, which means no more framework and plugins are needed.

Cons of AngularJS

  • Very complicated to understand.
  • Implementations scale is quite poor and rough,
  • If users disable the Javascript in Angular JS application, they can see the basics.

Pros of Angular

  • Typescript in Angular provides the code optimization with OOPS.
  • It offers Enhanced Dependency Injection with Modularity.
  • Follow the simple routing.
  • Developers get a chance to integrate the TypeScript, Dart, ES5, and ES6.

Cons of Angular

  • Quite complex to set up when compared to Angular JS.
  • Not an ideal choice for creating simple web applications.

Migrate From Angular JS to Angular

  • Most of the applications are easier to upgrade as compared to the others, there are multiple ways to Migrate From Angular JS to Angular such as:
  • Run two frameworks simultaneously in the same app, and migrate the components of AngularJS to Angular one by one.
  • With the help of module loaders like Webpack, SystemJS, or Browserify have the built-in module system which can be used to import and export features to multiple parts of the application.
  • Application having the component directives can be migrated easier to the Angular application with lower-level features like ng-includes, ng-controller and the scope inheritance.

The last words

AngularJS has still had its worth and every upgraded version bespeaks the quality, performance, and benefit of different verticals of the enterprises. So, Hire the Angular Developer and design the website or mobile application with distinctive features.
