Living in a digitalized world where everyone wants to opt for custom web application development and look for ways to make their digital presence notable, as a developer one needs to have sound command over the development tools, be it any computer language or a CMS. Likewise, AngularJS is an open-source front-end web framework based on Java-Script and is led by Google. It is best known for building single-phase applications and line of business application.
AngularJS has become known tools in the world of developers and is often asked about in the job interviews. Here is everything you need to know about it:
What is the difference between Angular and Angular JS?
Angular JS was the initial version of Angular, was released in 2010 by Google to address the challenges faced while developing single-page applications. It used Java as the primary programming language. A few years later, Angular 2 was released which used typescript as its primary language. Since then, more than four versions of Angular have been released, each one of them modified to cater aptly to the needs of developers. Angular is a broad term that is used to refer to all versions of it, i.e. Angular 2,4,5,6 and 7.
What is it used for mainly?
AngularJS is mainly used for developing Single Page Applications (SPA). Angular has a set of already existing modules that simplify the development process. AngularJS is regarded as a full-fledged framework that has built-in streaming, modular CLI and types safety.
What are the Main Features of AngularJS?
Here are the features that make AngularJS a powerful framework in the digital market:
- MVC: AngularJS is built on a famous concept, i.e. Model View Controller (MVC), a design pattern used in all modern-day web applications. This pattern splits the data layer, the business logic layer and presentation layer into separate sections. The division is done so that each one can be managed easily.
- Writing Less Code: Unlike other web application development frameworks, you will be required to write a lesser amount of code in Angular for DOM manipulation.
- Unit Testing: Google has not just developed Angular but has also created a framework called ‘karma’ for designing unit tests of Angular JS.
- Data Model Binding: With AngularJS, you won’t have to write any special code to bind data with HTML controls. Adding a few snippets of code will work well! Data binding has four types:
- Event Binding
- Two-Way Data Binding
- Property Binding
- String Interpolation
What are the Advantages of Angular JS?
Here are the few benefits of using Angular JS that distinguish it from other web application development frameworks:
- Less number of errors and minimal issues since it is an open-source framework
- In AngularJS, data and presentation layers are in sync. You won’t have to write additional codes to keep the data in sync. You will only have to specify which part is bound to which part of the model.
- It supports unit testing and integration testing.
- AngularJS takes care of routing, a key feature of single-page applications that allows the users to switch from one functionality to another yet staying on the same page.
- AngularJS has derivatives. They help in enhancing the functionality of existing HTML features which in turn gives more power to your web application.
What is AngularJS’s Architecture?
It follows the MVC architecture, i.e.:
- It has a controller that represents the logic layer. User events are part of the controller and trigger the functions stored in it.
- Views represent the presentation layer which is visible to the end-users.
- Whereas models represent data. The data in the model can be simple or complex, depending upon what it is representing.
What are templates in AngularJS?
In AngularJS, templates are written with HTML and have Angular-specific attributes and elements. Templates combine information coming from model and controller to provide a dynamic view to the users.
Conclusion: Since AngularJS is supported by Google and has ideas from a large community, therefore, it is up to date all the time. It is modified as per the trends of the development market. This information would be ample for you to have basic knowledge of the AngularJS.
