What is AngularJS?
AngularJS, also known as Angular 1.x, is a JavaScript-based open-source framework developed by Google. It was released in 2010 and gained popularity due to its ability to build dynamic and interactive web applications. AngularJS follows the Model-View-Controller (MVC) architectural pattern and relies on two-way data binding.
What is Angular?
Angular, commonly referred to as Angular 2+ or simply Angular, is a complete rewrite of AngularJS. It was released in 2016 and is also developed and maintained by Google. Angular adopts a component-based architecture and utilizes TypeScript, a statically typed superset of JavaScript, as its primary language.

Top 20 2023 Angular Interview Questions
Angular and AngularJS
| Feature | Angular | AngularJS |
|---|---|---|
| Framework language | TypeScript | JavaScript |
| Two-way data binding | Yes | Yes |
| Component-based architecture | Yes | No |
| Directive-based architecture | No | Yes |
| Community support | Active | Still active, but not as much as Angular |
| Performance | Faster | Slower |
| Learning curve | Steeper | Gentler |
Language: AngularJS uses JavaScript, while Angular uses TypeScript. TypeScript is a superset of JavaScript that adds static typing, enhanced tooling, and improved maintainability.
Architecture: AngularJS follows the Model-View-Controller (MVC) pattern, while Angular employs a component-based architecture. In Angular, each component represents a self-contained unit of UI and functionality, making code more reusable and modular.
Performance: Angular is known for its improved performance compared to AngularJS, thanks to its optimized rendering and change detection mechanisms. Angular also supports lazy loading, which can further improve performance by loading only the necessary components when needed.
Mobile Development: Angular offers better support for mobile development through frameworks like Ionic. Ionic allows you to build native-looking mobile apps using Angular components. AngularJS does not have native mobile development capabilities, but there are third-party solutions available.
Community Support: Angular has a larger and more active community compared to AngularJS. This means that there is more documentation, resources, and third-party libraries available for Angular.
Which one should you choose in 2023?
Choosing between Angular and AngularJS depends on a number of factors, including:
- Project size and complexity: For small to medium-sized projects, AngularJS may be sufficient, especially if you have an existing codebase. However, for larger and more complex applications, Angular’s improved performance, scalability, and maintainability make it a better choice.
- Learning curve: If you are already familiar with AngularJS, transitioning to Angular may require a learning curve due to the architectural and language differences. However, investing time in learning Angular can be beneficial in the long run, considering its popularity and community support.
- Long-term support: AngularJS is in Long Term Support (LTS) mode, meaning it will receive critical bug fixes and security updates until June 30, 2023. Beyond that, it is recommended to migrate to Angular for ongoing support and access to the latest features.
- Community and ecosystem: Angular has a vibrant community and a vast ecosystem of libraries, tools, and resources. This can significantly aid in development, troubleshooting, and finding solutions to common challenges.
Overall, Angular is the recommended framework for new projects in 2023. It offers improved performance, scalability, maintainability, mobile development support, and community support.
However, if you are working on a small to medium-sized project with an existing AngularJS codebase, AngularJS may still be a viable option.

FAQs
-
What is the main difference between Angular and AngularJS?
Angular is a complete rewrite of AngularJS and introduces significant changes in terms of architecture, language, and performance. AngularJS is based on JavaScript and follows the MVC pattern, while Angular uses TypeScript and follows a component-based architecture.
-
Which version of Angular should I use?
If you are starting a new project in 2023, it is recommended to use the latest stable version of Angular, which is Angular 12 at the time of writing. Using the latest version ensures access to the latest features, bug fixes, and security updates.
-
Can I migrate my AngularJS project to Angular?
Yes, it is possible to migrate an AngularJS project to Angular. However, the migration process can be complex and time-consuming, depending on the size and complexity of your project. It is recommended to plan the migration carefully and consider seeking assistance from experienced developers or migration tools.
-
Is AngularJS still supported?
AngularJS is in Long Term Support (LTS) mode, which means it will receive critical bug fixes and security updates until June 30, 2023. After that, there will be no official support from the AngularJS team. It is advisable to migrate to Angular for ongoing support and access to the latest features.
-
Which framework is better for performance, Angular or AngularJS?
Angular generally offers better performance compared to AngularJS. Angular’s optimized rendering and change detection mechanisms contribute to improved performance. However, it is important to note that performance can also depend on factors such as code quality, implementation, and optimization techniques used in your specific project.
-
Can I use AngularJS and Angular together in the same project?
While it is technically possible to use AngularJS and Angular together in the same project, it is not recommended. The two frameworks have different architectural patterns and language requirements, which can lead to conflicts and complexities. It is advisable to choose one framework and migrate your codebase accordingly.
-
Which framework has better community support, Angular or AngularJS?
Angular has a larger and more active community compared to AngularJS. The larger community translates to better documentation, resources, and third-party libraries. You can find numerous tutorials, forums, and online communities dedicated to Angular, making it easier to find solutions to common challenges.
-
Can I use AngularJS components in Angular?
AngularJS components cannot be directly used in Angular due to the architectural differences between the two frameworks. However, there are migration strategies and tools available to help you gradually migrate AngularJS components to Angular.
