Here is the detail information about the Angular Vs. AngularJS Frameworks. Find the Pros and Cons & Advantage & more about angular & JS.

Angular Vs. AngularJS Frameworks

What are the differences between Angular Vs Angular JS? One of the major distinctions between the two frameworks is that Angular is written in TypeScript and Angular JS is written in JavaScript programming languages. One similarity is that they are both front-end and open-source platforms that are perfect for building Single-page web applications.

What is Angular Vs. Angular JS?

Angular JS or Angular 1 came before Angular, and it was created in 2009 by two developers, Misko Hevery and Adam Abrons

Before going into details of the differences between the two frameworks, we shall go back to the beginning. Angular JS or Angular 1 came before Angular, and it was created in 2009 by two developers, Misko Hevery and Adam Abrons, who had named it GetAngular Abron abandoned the project and Hevery started working on a Google project named Google Feedback. Hevery and Brad Green, redid the original project, named it AngularJS and assembled a team to maintain the project within Google.

Angular JS is a client-side and MVC (Model Control View) framework which does not need to communicate to a server for HTML reload implementation. Still, its website rendering is faster and more reliable. In 2016, the release of Angular 2 saw a complete rewrite of the framework, which became known as just Angular.

The Angular framework is excellent for building SPAs via TypeScript and HTML syntax. Angular itself, as mentioned before, is written in TypeScript from Microsoft. An Angular app’s architecture depends on some basic concepts. The Angular framework is made up of components called NgModules. These modules collect all relevant and related codes and group them into sets. NgModules define Angular apps, and an app always contains a root module. The root module allows bootstrap and has more feature modules.

The Major Differences Between Angular Vs. Angular JS

Besides the programming language differences, the two frameworks have many other differences.

1. Angular Vs Angular Js Components

Angular Vs Angular Js Components

When one framework is written in JavaScript and the other TypeScript, the difference lies in their components. TypeScript used by Angular is an ES6(ECMAScript 6) superset, which has backward compatibility with ES5. TypeScript is a superset of JavaScript and enables static typing while developing an app. JavaScript or JS is a unique language because it has full CSS and HTML integration.

Static typing allows for better performance and avoids the mistakes in runtime that made AngularJS difficult for larger apps. Angular JS is a JavaScript framework and uses controllers and terms of scope, while Angular utilizes a hierarchy of components. Angular uses components while Angular JS is directives-based.

2. Use of Directives

Both the Angular and Angular Js frameworks use Directives, but the difference is in how they use them. Angular contains standard Directives and Angular JS contains a pack of Directives. While using Directives, caution is important.

For example, when creating a two-way binding in AngularJS, you must use the ng-model, while in one-way binding, you can use ng-bind. Angular contains the ngModule, and you have the liberty to utilize the one-way binding symbols appearing “[]” and two-way binding “[()]. “[]” is equal to property binding and “()” equal to event binding. In Angular, some names of directives have changed, such as ng-repeat to ngFor.

3. Architecture

· Angular

Angular makes use of components, which are directives that have templates. In Angular, there are two types of directives:

  1. Structural Directives, which change the DOM’s structure by replacing the elements
  2. Attributive Directives, which alter how the DOM behaves and the element appearance

4. AngularJS

Angular has a built-in DOM and Angular Universal State Transfer API, which helps the developer in easier app sharing between ck] client and server-side.

The AngularJS framework has an MVC (model-View-Controller), which operates as a pivotal component by managing logic, rules, and data, as well as expressing the application's behavior.

  • Model: Where data management is stored
  • View: After the information review in the model, it generates some output
  • Controller: The controller converts the input, converting it into commands, which it relays to both the Model and View.

5. Performance

AngularJS was initially developed with designers in mind. The newer versions have seen an upgrade to allow them to provide better performance in terms of dependency injection and speed.

· Speed

The provision of features such as two-way binding allowed AngularJS to reduce the time and effort spent in developing an app. By the creation of added processing to the client-side, page loading took a long time. Angular 2 is faster than AngularJS, and a much better and faster structure for easier creation, large application maintenance, and improved change detection mechanism.

For two-way binding implementation, AngularJS regularly checks every scoped variable with its predecessor value via a digest cycle. The digest cycle is run at random, and as the program size expands, the checking can wind on indefinitely, making the app performance slower.

The Angular architecture is fluid, and change detection is carried out via unidirectional data flows, making the apps much faster.

· Dependency Injection (DI)

Both frameworks use dependency injection, albeit differently. In AngularJS, dependency injection is inserted into directive definitions, and different controller and link functions. Angular uses a hierarchical dependency injection system by use of the provider, constructor functions, and declarations.

6. Mobile Support

Angular is capable of building mobile supported apps on Android and iOS, while AngularJS code does not have mobile support, both Android and iOS.

7. Angular CLI

Angular has its own CLI (Command-line Interface). The CLI is used for the generation of services, components, etc., and completes projects efficiently and fast. You can effortlessly generate various versions of a single project for varying platforms with linting, type checking, etc. The interface scaffolds and develops Angular applications via node.js method of modules on the other hand, AngularJS does not have its own CLI.

8. Tool Support

AngularJS depends on third-party tools such as WebStorm and IDE, while Angular uses the CLI for reducing the time and effort spent in creating apps.

9. SEO Optimized

For the development of an SEO optimized AngularJS application, HTML rendering on the server-side is a necessity, while on Angular 2 it is not.

10. Router

In AngularJS, a router is configured using $routeprovider. When () while Angular is @RouteConfig {(…)}

11. Animation Package

In AngularJS, the animation code is included in the app, whether it is needed or not. In Angular, the developer does not necessarily have to download huge files.

Angular Vs AngularJS Pros and Cons

Both these frameworks have their advantages and disadvantages. To make a better decision on which framework is the best for your project, here are some advantages and disadvantages of both.

· Angular

Pros

· Modularity

Angular’s functionality shifted to other modules, creating a faster and lighter core.

· Dynamic Loading

For reactive programming, there is combined asynchronous templates and extra support

· AOT (Ahead of Time)

This compilation allows the conversion of TypeScript and HTML into JavaScript during the development process. AOT does the code compilation and the browser loads the code for faster and effortless rendering.

12. CLI

The Command-Line Interface helps in creating and serving angular apps. It tends to the project building and improves testing accessibility.

· The Architectural Component

This component allows for the division of logical and functional components

· Dependency Injection (DI)

Angular makes use of unidirectional change detection. Instead of using directives like AngularJS, Angular uses Hierarchal dependency injection, which improves its performance

Language Options

Angular is written in TypeScript but provides other language options for writing code like Dart, ES5, and ES6

Routing

Angular’s path is uncomplicated. It interprets a URL as a navigation directive to a client-view

Advantages of Angular JS vs Angular

  • MVC: The Model-View-Controller utilized data binding for speeding up application development
  • The POJO models and the two-way data binding gives a user interface that allows developers to use fewer code lines in their projects
  • AngularJS comes fully equipped with a unit tester that is upgraded frequently. The developers use their code to trace any defects in their designs.
  • AngularJS has a solution for front-end development as it does not rely on other plugins or frameworks.
  • AngularJS uses the HTML declarative language, which makes it very intuitive
  • Angular gives users’ re-usable components
  • The AngularJS architecture is simpler for the fast development of mobile and web applications.

AngularJS Cons

  • A developer not conversant with the MVC architecture cannot use AngularJS
  • The system can only be used with JavaScript, and cannot run if JS is disabled.
  • The Directives and DI (dependency injection) feature can feel complex to a developer used to the conventional methods. You might waste too much time on tutorials and you might have to hire someone.
  • If you are a newbie to the framework, the scopes debugging will feel complex.

Should You Choose Angular or AngularJS?

After going through the exhaustive list of the pros of the Angular framework, it seems to make more sense to choose it. However, Angular has a steep learning curve, and if your app is straightforward and simple, you might be better off using AngularJS, which will make it faster and easier to develop. If your project is complex and needs to be scalable, Angular is the best choice.

Should You Choose Angular or AngularJS?

Considering Angular’s steep learning curve, you have the option of using tutorials to learn more about using the framework, outsourcing to an angular development company, or hiring an in-house Angular team if you have a budget that allows for it. For web developers or an entrepreneur, Angular is bound to give you a good ROI.

The Future of Angular

When Angular was released, it became very popular in the software development industry. The popularity was for its built-in features like two-way binding, responsive designs, and the ability for developing responsive web apps.

When front-end frameworks such as ReactJS, which performed better were introduced, Angular's disadvantages came to the fore. AngularJS’s rewrite to Angular 2, tried to give developers an improved alternative. Angular 4 was released in 2017 and was backward compatible with Angular 2.

Web app development is nowadays much easier and more secure. The applications have become more flexible, secure, and scalable. You can upgrade to the latest version of Angular you want, as Angular provides among the best options for building large apps.

Angular is an excellent framework and Google moved to Typescript to improve code maintenance and app performance. There has been a great deal of improvement in the Angular framework, and it has become efficient and faster.

In 2018, a StackOverflow Developer Survey revealed that both frameworks were the second in the most used technology in Libraries and frameworks. At that time, 36.9% of engineers were using AngularJS for creating dynamic web apps.

Conclusion

There is a growing need for web development of apps by companies, especially in the wake of e-commerce. As more businesses get their businesses online, the more dynamic apps they need. Both of these frameworks are exceptional apps in their own right. It all depends on your business needs and the size of your app. Either way, you cannot escape the fact that building web pages and apps are fast becoming a necessity for business owners.

To this end, the Google development team is working at reducing the Agular apps build size, and improving their performance.
