In this digital era, thereâs competition among the frameworks for being one of the best frameworks for creating a Single Page Application (SPA). As a result, you will find a plethora of frameworks that help you (a developer) to overcome development complexity and build robust web applications for a single page.
Among them, you may come across two widely popular frameworks â Angular and AngularJS, which have created a buzz in the dev community for developing single-page applications.
If you are a novice or a layman, you may get confused with the name of these two frameworks. However, they often consider both of them to be the same. But the reality is something different.
In fact, Angular and AngularJS are different frameworks in reality. But the purpose of both these frameworks is for front-end development.
However, we hate confusion, donât we?
And understanding these two frameworks will help you decide which could be the better choice for your front-end development.
Hence, in this blog, we will discuss - what is Angular, what is AngularJS, the difference between Angular and AngularJS, and everything that is required to clear your doubts.
So, without further ado, letâs get you there.

AngularJS is an open-source JavaScript framework suitable for front-end web development and creating Single-Page Web Applications. Developed by Google, AngularJS uses HTML as its template language, which makes AngularJS intuitive to use.
Built upon the Model-View-Controller (MVC) architecture, the primary objective of AngularJS is to build a Single Page Application (SPA). Moreover, AngularJS offers a ready unit testing feature with continuous updates, allowing developers to identify bugs in their code quickly.
Due to the simple architecture of AngularJS, developers can easily build mobile and web applications quickly. The MVC structure also enables you to enhance the development speed and create an interface with a minimal codebase due to the two-way data binding feature.
One of the most mind-blowing facts about AngularJS is that itâs the first-ever version of Angular. It means all the 1.XX versions are referred to as AngularJS, and it is also known as Angular 1. Besides, version 2 and subsequent versions are known as Angular.
It all started back in the summer of 2009 with two developers â Adam Abrons and Misko Hevery. They were working on a side project called GetAngular, and their goal was to make the whole web app development process easy for web designers without the need to have a coding background.
Once it was possible to reduce 17000 lines of code to only 1500, Google recognized its capability and created a framework of its own.
That framework was AngularJS, named after the sharp angles of the most popular brackets in the coding world (</>). Soon, it gained massive fame as a structural framework transforming static web pages with its robustness. Above everything, it made building web apps much faster and easier.
AngularJS was the way to go, and no one had any difficulty understanding that.
Eventually, the world the JavaScript sped up and developed. A lot of problems that AngularJS resolved became dispensable, such as making the managing of DOM much more seamless. Additionally, AngularJS lost many of its benefits as new technologies kept popping up following the rise of this framework.
Google would have simply improved the framework, but they considered it a worthless approach.
So, they decided to recreate it from scratch in 2014.
AngularJS was very demanding and adopted in the development community to build performance web applications before the release of Angular 2. The reason behind its popularity is its wide range of features that allows faster development and ensure better code maintainability.
Here, letâs look at the features of AngularJS in detail:
AngularJS framework uses plain JavaScript programming language. Hence, the models in AngularJS are plain JavaScript objects.
We know JavaScript is the most popular programing language in the world compared to TypeScript. Therefore, it becomes quite easy for professional web developers to utilize it for web application development with a lower learning curve.
As a result, developers can easily test and maintain the code with AngularJS.
The controllers and directives in AngularJS let you have complete control over the application behavior and choose the functionality.
When it comes to the controllers, it defines the behavior of the DOM element. This behavior helps you decide how DOM elements should perform under specific circumstances. Besides, directives are directly added to the HTML code to integrate certain functionality into the application.
It's important to remember that while directives are used directly within the (HTML) templates, controllers are built independently.
AngularJS gives you the prime feature â reusability of components. This allows you to create reusable components using directives and utilize those components many times within an application. A component defines a particular functionality of the application.
The routing feature of AngularJS allows you to switch between different views of an application easily. In short, routing enables users to navigate through different pages of a website or a web appâs sections.
AngularJS outshines multiple web development frameworks, providing many advantages to its widespread adoption. Let's now explore the key benefits that make AngularJS a top choice for developers:
After going through the advantages, itâs now time to understand the disadvantages of AngularJS.
Leverage the Benefits of AngularJS Development for Your Business Needs
Let's Begin
Hereâs a little secret to share with you in this discussion of the difference between AngularJS vs Angular.
Angular is an open-source front-end framework that helps developers with single page app development services. Angular is a TypeScript-based web framework with a modular design that uses HTML and TypeScript.
Since TypeScript is a superset of JavaScript, it has all the capabilities that JavaScript possesses with additional features. The primary objective of Angular was to develop fully functional web applications.
In fact, modern browsers donât understand TypeScript; therefore, here, TypeScript is converted into JavaScript so that browsers can easily compile the application written in TypeScript. This is the main difference between Angular and AngularJS.
In September 2016, Google first released Angular for public use. The base version of Angular is Version 2. The latest version of Angular is Angular 17.
Previously, everyone used to call AngularJS simply Angular. At first, they decided to name the rewritten version Angular 2, but since it could spark a big confusion among developers, they added a new suffix to the previous version - âJSâ. And âAngularâ was only the term for all the new versions.
As you can see, the âJSâ suffix largely stands as the biggest differentiator between Angular and AngularJS: Angular is based on TypeScript, while AngularJS is based on JavaScript.
And this change came from the difference between TypeScript and JavaScript.
As TypeScript is more capable of handling large-scale projects, especially if many teams need to work on a single project, Angular is one step ahead in the game. Apart from the usual JavaScript ones, its other benefits include â advanced navigation and autocompletion, easier identification of bugs, higher code readability and predictability, static typing, fast and safe refactoring, etc.
If you want to develop dynamic web apps with efficient behavior and modern design, Angular is the ideal option for you. As it has a modular nature, you can break down the whole app into individual modules, each representing a specific functionality.
Boiling down, this framework makes it possible to build high-performance web apps without much difficulty while providing two-way data binding and adhering to the MVC architecture.
With a plethora of features, Angular has turned out to be the most powerful JavaScript web application framework. The Angular framework enables developers to build modern and high-performance applications, which makes the development process easier.
Letâs figure out the most important features of Angular:
The cross-platform web application framework - Angular allows you to create intuitive UIs for desktop, web and native mobile applications. Moreover, Angular is the right choice if you are planning to develop applications for macOS, Windows, and Linux operating systems.
Angular uses TypeScript as a programming language, which is better than JavaScript due to its statically-typed language nature. As a result, developers find fewer errors during the compile time as the types of variables are pre-defined. Also, the code of JavaScript is valid TypeScript code.
Angular comes with an Angular CLI feature, which enhances the development process. With the installation of Angular CLI in your system, you can perform multiple tasks, from configuring the project to adding components.
Data binding feature of Angular allows you to include dynamic behavior in Angular web pages. Moreover, developers have to use () for event binding and [] for property binding in Angular, whereas AngularJS uses the NG directive approach to perform data binding.
In most cases of Angular, two-way data binding occurs between model and view components.
Angular lets you perform unit testing without any issues. As a result, it delivers a bug-free outcome. The web framework â Angular uses the Karma test runner for quick and easy debugging.
Angular was designed from scratch to support mobile application development. It offers a wide range of features, like touch-based gestures and responsive layouts, to build mobile applications.
Letâs go through the advantages of Angular:
Now is the time to understand the disadvantages of Angular:

Today, Angular has earned its place as one of the most renowned frameworks among developers around the world. Angular has almost 33,76,508 npm weekly downloads and is utilized by more than 2.7 million GitHub projects.
We can consider Angular future-proof due to the vigorous support from the tech giant Google. Apart from using this technology in their own products like Google Analytics, Firebase, or Google Cloud Console, they also use it for internal use. Switching to another technology at this point of time can be very time-consuming and costly; hence, you can rest assured that Angular will not leave us any time soon.
It has emerged as a hefty competitor to both Vue and React, giving rise to the Angular vs React vs Vue dispute in the development sphere.
On the other side of the AngularJS vs Angular discussion, AngularJS is presently on LTS (Long Term Support). It encourages developers to check out the latest versions of Angular - Angular 15 with its official site. Such an official suggestion straight from the Google house should resolve the argument of which version is more useful.
Although these two frameworks share some common characteristics as Angular is the revamped version of AngularJS, the former was released as a major update of the latter with a lot of added functionalities and changes. Hence, Angular is purposefully different from its former version and Angular is still relevant in 2025.
Here are the key factors that represent the grave difference between Angular and AngularJS in detail:
While talking about the difference between Angularjs and Angular, AngularJS uses a Model-View-Controller design pattern. The primary objective of this architecture is the separation of concern, meaning you can divide the web app into three distinct components:
It's technically the back-end that manages and stores the data.
It's technically the front-end that displays all the data in the form of user interfaces.
It controls and requests data from the Model to upgrade the view once users interact with the UI.
Angular replicates this MVC pattern to a certain level with templates as the view and directives and components as controllers. It also shares some commonalities with the Model-View-View design pattern. But at its core, the architecture of Angular is component-based which allows you to keep the logical and functional components separate from each other.
The ngModules
of this framework will help you assemble code chunks (whether they are services, pipes, directives, or components) as per their functionality, leading to a greater extent of abstraction. Such a modular nature of top AngularJS development tools significantly invokes scalability and reusability, making it a perfect choice for large-scale projects.
Coming to the second point of AngularJS vs Angular topic, we must mention the prefix ng
â one of AngularJSâ vital features that represent directives. Directives enable you to add defined behavior to DOM components and extend the HTML.
To give you an example:
ng-disabled
identifies whether a component is disabled or not.ng-value
determines the value of an input component.ng-blind
replaces the value of an HTML component with the given value of the expression.Moreover, you can create custom directives and name them as you wish in case you cannot find built-in ones.
Now Angular projects also have the ng
prefix but donât let it fool you. Yes, they are also directives, but you have to use them in an entirely different method. Based on their purpose, we can categorize them into three classes:
You can change the structure and design of the DOM layout with these directives. For instance, a ngSwitch
removes or adds DOM components, and ngIf
removes or displays a component after it meets a specified condition.
You can change the behavior or appearance of DOM components with attribute directives. For instance, a ngMode1
adds two-way data binding to an HTML form component, and ngClass
removes or adds CSS classes.
Component directives are the most common type that consists of templates. Templates are the fundamental units of Angular.
Dependency injection is the most critical functionality of AngularJS and a key factor in Angular and AngularJS difference. This technique allows objects (clients) to depend on other objects (services) without informing clients about the external code (injector). Besides, clients should only use services without knowing how they are constructed.
Let's explain this with a real-life analogy:
Suppose an employee (client) is on their first day of work. They need their own software and hardware to do the work, but instead of bringing any of their own, the employee depends on the employer (services) for the resources.
Additionally, the employee has no idea about what they are about to get (injector), and honestly, they donât care. They will use whatever the employer will give them without asking for details.
Readability and reusability are the greatest benefits of dependency injection. It also enforces the importance of software testing and maintenance for your product.
Talking about Angular, it also has dependency injection but with two major differences that fuel the Angular vs AngularJS discussion.
Build a High-Performance Application with the Help of AngularJS

Between the View and the Controller in AngularJS stands the scope ($scope
). Its purpose is to help data in passing between the elements of the View and the Controller. The scope also works as a data source, and in that way, it resembles the Model. Itâs accessible to every object in your project.
In the case of Angular, just like it no more needs the Controller, it does not share the data in the same way as AngularJS does. Instead, as a component-based framework should, it entirely depends on components.
If so, how will you share data then? Angular offers you multiple ways to do that. You can use:
@viewChild
@input()
)SharedService
)ngOnChanges
to cut off input property changesAnd to identify changes, Angular uses ngZone
.
The process of data binding plays a big role in the Angular JS and Angular difference.
AngularJS made a great impact on the IT verticals with its two-way data binding feature. If there is a new change made to the view (user interface) or Model (data), both of them will get automatically updated by synchronizing in two directions.
Hence, the top AngularJS frameworks for web development came with the two-way data binding feature, and it was the best bet as long as you cared about updating everything at all times. Moreover, it minimized the amount of necessary code as well.
But it had a downside of its own.
The disadvantage of this process is that every update triggers a series of events such as dirty checks and callbacks â $watch
observes each $scope
, and after itâs triggered, it runs the $digest
cycle that updates the DOM.
The number of watchers and the size of your project will be directly proportional; meaning, the larger the product, the more watchers there are in the observation role. This can drastically decelerate your web app and could lead to disastrous results if in unskilled hands.
This is where Angular revolutionized the data binding process by introducing one-way data binding.
Since one-way data brought down the number of DOM updates, it gave up the automatic synchronization for enhanced performance. It can either bind the data from the DOM to the component or vice versa, but never both. Angular provides several techniques of data binding such as event binding, property binding, class binding, and so on.
But the process of two-way data binding is not totally absent from Angular. You would still find it useful, especially if your project needs strict data accuracy. ngModel
can help you do it. Keep in mind that you will notice a different expression syntax â in Angular, you use [] and (), whereas in AngularJS, you use {{}}.
CLI is an amazing tool that stems from the difference between Angular and AngularJS. You will not find this tool in AngularJS. Angular introduced it with the goal of remarkably reducing the effort and time throughout the project. CLI will help you with testing, maintenance, deployment, scaffolding, and setting up the environment.
If you are a beginner in this field, CLI can be highly useful as it configures all the required dependencies for you, as well as ensures you are abiding by the best practices.
In a nutshell, CLI will take care of all the heavy lifting for you, empowering you to focus on the code quality and coding standard in software development that matters the most.
While the CLI tool in Angular is optional, we would highly recommend you utilize its benefits.
If you are planning to develop a SPA (Single Page Application) just like Facebook (excuse us, Meta), you donât have much choice but to incorporate routing. Routing is imperative for creating the illusion of swapping different pages, but in reality, users stay on the same page. Only what is visible changes, not the page.
If you want to pull off this routing effect with AngularJS, you have to use the module <a href="https://docs.angularjs.org/api/ngRoute" target="\_blank" rel="noreferrer noopener">ngRoute</a>
and the service $routeProvider
to configure.
For basic requirements, this is the best solution, but you might face some limitations along with the advancement of your project. For example:
Such limitations arise because the native routing of AngualrJS is determined from template to URL routes and assigning controllers. This is the reason AngularJS cannot win against a third-party tool called UI-Router â an openly acknowledged quality choice for routing.
Hence, if you are struggling with the issues mentioned above, you can seamlessly switch to the UI-Router as it can resolve them all.
On the other hand of this Angular vs AngularJS analysis, the prior comes with a different approach to routing. It has its own built-in routing - @angular/router. As Angular is a component-based framework, its components are capable of managing their own sub-routes, eliminating the need for global router configuration.
In addition, all routing is static, resulting in less bandwidth consumption, assured predictability, and smooth maintenance for large networks.
While talking about Angular JS vs Angular, Angular offers mobile support.
On the other hand, AngularJS does not.
The dissimilarity is the outcome of different times â mobile support was not a critical criterion when AngularJS got first released. But now, it is a prerequisite.
Angular is able to tackle this problem just fine. It was always possible to develop powerful mobile apps using NativeScript ever since its inception. And in case you are a fan of the ionic framework, you can use it with Angular 6 and up versions.

While talking about Angular and AngularJS difference, there are still a great number of AngularJS developers. More importantly, there is still a wide array of apps and sites created with this technology. Since everyone does not have the resources and means needed for such a huge upgrade, we can still find AngularJS in the trenches.
So, if you have the slightest doubt regarding whether we should still make the comparison, the answer is yes. Comparing these two technologies is worth the effort since most people still tend to confuse them.
Final Thoughts on Angular vs AngularJSAngularJS shook the development world by saving us from the dread of jQuery's spaghetti code, so itâs never a wise decision to let it go.
