Differences Angular JS and Angular
Angular JS is a JavaScript-based framework well known for creating dynamic web applications. It uses HTML for template development. Directives in Angular JS enable it to develop code that is reusable as well as modular. Angular is a prominent open-source JavaScript framework created for developing web applications. Frontend developers need to select one of its versions for proceeding with their project development. Angular provides hierarchy based architecture by supporting the hierarchy of components which is directive with templates.
Let us study much more about Angular JS and Angular in detail:
- Angular JS, also known as Angular 1, was developed by Google in the year 2009 and released it in 2012 as version 1.0. Angular became one of the most widely used open-source JavaScript frameworks on both enterprise levels and individual front-end developers. Angular does not provide the feature of scope or controllers. Consequently, its different versions have been released with incremental features from Angular JS version 1.0 to Angular version 2.0 and currently have the version of Angular version 4.0.
- Angular JS supports HTML attributes with directives and provides data binding between data and HTML with expressions that result in an easy to read, highly expressive and faster-developed platform.
- Angular refers to a blanket term used for Angular 2, Angular 4 and all other versions that emerged after Angular JS. Angular 2, along with Angular 4, is an open-source and TypeScript based platforms used for UI applications. Angular 2 is completely re-created on Angular JS. Angular 4 has some additional features and has backward compatibility with Angular 2. Angular also supports ES6 features like reflection’s mechanism or iterators, lambda operators, etc., as it’s a typescript based framework.
- Angular JS gives the developers the ability to write an application based on MVC or MVVM architecture (also known as MVW(Model-View-Whatever) architecture). Angular JS has the feature of dependency injection, which supports the mechanism of mocking dependencies.
- Angular JS uses the concept of scope and controllers. Developers can add many variables that have their scope in View as well as Controller. Angular JS also has a feature called as rootScope. Variables added in the rootScope can be available overall application.

Key Differences Between Angular JS and Angular
Below are the lists of points, describe the key difference:
- Angular JS denotes version Angular 1.x where JS stands for JavaScript.
- Angular denotes version 2 and higher versions that use TypeScript.
- Angular JS is an open-source, JavaScript framework, can be freely used, shared by everyone for developing web applications.
- Angular is lightweight, supports most of the major browsers and used for developing testable JavaScript code.
- Angular JS supports great MVC data binding that helps in faster application development.
- Angular JS provides a complete rapid frontend development solution without the use of any external plugin or framework.
- Utilising HTML as a declarative language makes Angular JS easy to understand the framework.
- Angular JS applications can be executed on all major platforms, including iOS and Android-based phones and tablets.
- On disabling the JavaScript in Angular JS, a basic page will be displayed only.
- TypeScript feature in Angular 2 allows code optimization with the help of object-oriented programming concepts.
- Angular 2 provides a better way of dependency injection and code modularity.
- Angular 2 supports multiple programming languages, including Dart, TypeScript, ES5, and ES6, for writing programs.
- Angular 2 uses a simpler routing mechanism.
- Angular 2 is more difficult to set up in contrast to Angular JS.
- Angular 2 is less efficient for creating small applications.
- In Angular, hash(#) is used to define local variables.
- Angular 4 is a complete TypeScript used for building large and complex applications.
- Tests in Angular 4 are easier to write in comparison to other versions.
- Angular 4 comes with a modularised animation package.
- Angular 4 provides the View engine with better performance that helps to generate less code in AOT mode.
- Angular 4 is efficiently used for application with a single page and extended interface.
- Angular JS becomes slower for displaying the bulk volume of data.
Angular JS vs Angular Comparison Table
Following is the set of points shows the comparison:
| BASIS FOR
COMPARISON |
Angular JS | Angular |
| Architecture | Supports Model-View-Controller design. The view processes the information available in the model to generate the output. | Uses components and directives. Components are the directives with a template. |
| Language | Written in JavaScript | Written in Microsoft’s TypeScript language, which is a superset of ECMAScript 6 (ES6) |
| Expression Syntax | Binding of an image/property or an event, a developer needs to remember the right ng directive. | Uses “()” for event binding and “[ ]” for property binding |
| Mobile Support | Does not provide mobile support | Provides mobile support |
| Routing | Uses $routeprovider.when() for routing configuration | Uses @Route Config{(…)} for routing configuration |
| Dependency Injection | Does not use dependency injection | Uses hierarchical dependency injection system with unidirectional tree-based change detection |
| Structure | Less manageable in comparison to Angular | Better structure, easier to create and maintain large applications. |
| Speed | Reduced the development effort and time due to its feature of two-way binding | Angular 4 is the fastest version yet. |
Conclusion
Angular JS has got popularity because of its inbuilt features and ability to develop reactive and responsive web applications. When Facebook introduced its frameworks like ember.js and react.js in the year 2014 with better performance and outcomes, it highlighted the drawbacks of Angular JS to the developers. Because of which, the Angular team launched a completely new and re-written framework instead of upgrading the existing Angular JS framework. After that, it was decided to launch a new Angular version every six months, an upgraded version of the existing one and not the re-write. The current existing version of Angular is 5. Since Angular is the re-write of Angular JS, all the applications created using Angular JS had to develop again from the beginning to update the application. That has become a challenging task for the developers. Also, Angular is comparatively much efficient in terms of performance and provides developers with an end-to-end and complete solution from testing to hybrid apps to animations. Angular is proved to be one of the most beneficial frameworks, especially for building large and complex applications. Angular 4 provides an inbuilt compiler to catch the template errors within then IDE. Angular 4 comes with improved tooling techniques and reduced code size.
