It is MVC( Model, View, Control) Javascript Framework by Google for Rich Web Application Development.- AngularJS is a Javascript open-source front-end framework that is mainly used to develop single-page web applications(SPAs).
- It is a continuously growing and expanding framework which provides better ways for developing web applications.
- AngularJS is a JavaScript framework that is mainly used for Frontend Development.
- It is used for making Single Page Applications(SPA).
- It is open source and is completely free for everyone.
Why use AngularJS?
- Easy to work with: All you need to know to work with AngularJs is basics of HTML,CSS and Javascript,not necessary to be an expert in these technologies.
- Time-saving: AngularJs allows us to work with components and hence we can use them again which saves time and unnecessary code.
- Ready to use template: AngularJs is mainly plain HTML, and it mainly makes use of the plain HTML template and passes it to the DOM and then the AngularJS compiler. It traverses the templates and then they are ready to use.
AngularJS features:
Seamless Data Synchronization:
Two-way data binding: Ensures effortless updates between model and view, eliminating manual synchronization efforts. Modifications in one instantly reflect in the other, fostering a cohesive user experience.
Organized Structure for Enhanced Maintainability:
MVC architecture: Fosters a clear separation of concerns, dividing applications into model, view, and controller components for modularity and easier management.
Customizable HTML with Directives:
Directives: Extend HTML with custom attributes and elements, enabling dynamic content creation, template manipulation, and reusable components.
Cross-Browser Compatibility:
Not browser specific: Guarantees seamless functionality across diverse browsers, eliminating compatibility concerns.
Effortless Navigation:
Routing: Facilitates smooth transitions between views within a single-page application using the ngRoute directive, delivering a fluid user experience.
Simplified Development and Testing:
Dependency injection: Streamlines component management and testing by injecting dependencies into modules and controllers, promoting code reusability and maintainability.
Optimized Performance:
Speed and performance: AngularJS excels in delivering fast and responsive web experiences, ensuring optimal user engagement.
User-Friendly Bookmarking:
Deep linking: Enables direct linking to specific application states, preserving URL integrity for effective bookmarking and sharing.
Advantages of AngularJS
Some advantages of AngularJS are the following:
Without the involvement of a developer, bi-directional data binding in AngularJS development allows quicker and simpler data binding.
Change detection and unit testing are always possible with backward compatibility.
The AngularJS MVC and MVVM paradigms separate design data from design, simplifying the structure and care of challenging AngularJS websites.
Thanks to the open-source framework, the lack of other platforms or plugins makes the front-end development process more clear.
When AngularJS code is neat and well-structured, it is more reusable.
The performance and speed of AngularJS are better.
JavaScript is a dynamically typed language, and Angular is a JavaScript framework. Due to this, angular has a powerful expressive capacity. However, angular lacks compiler assistance. Robust test code must be written for it as a result. It is simpler to test individual code components because dependency injection is built into the system. Also, Angular supports both unit testing and integration testing.
Angular JS is simple to extend because of some built-in features. With the use of these built-in features, HTML's functionality can be increased by coupling a particular behavior to it. It is customized since one can add their own commands to it. Here, customized refers to modifying existing features or capabilities in order to meet unique requirements. Additionally, as customized software is created solely for each client, it includes user-friendly features rather than extraneous components.
Disadvantages of AngularJS
Some disadvantages of Angular JS are the following:
Knowing the MVC architecture is required for using Angular JS.
The AngularJS application is complex because it has multiple ways of taking out the same process.
Its poor performance of scalability and improper one-way binding for mobile browsers are two of AngularJS's notable flaws.
Users can access a simple page when third-party javascript tools are removed in an AngularJS app.
If JavaScript is disabled on the compuer where the AngularJS application is to run, it will not work.
When using the Angular JS framework for the first time, debugging the scope can be challenging. Developers must therefore train themselves before taking on a project.
Every framework has some differences that one must learn to use.
Limitations of AngularJS
Some limitations of Angular JS are the following:
When the javascript tools are removed from the Angular JS application, you cannot create a dynamic application.
Because AngularJS is a JavaScript-only framework, it is not safe. To keep an application safe, server-side authentication and permission are essential.
Memory leaks are a problem in JavaScript. Memory leaks are instances where an application no longer needs memory and, for a variety of reasons, the memory does not return to the pool of available memory. Memory leaks also cause other problems like slowdowns, crashes, and high latency.
Angular JS is not supported everywhere. For example, Angular Js is incompatible with Internet Explorer 8.0.
The rendering of websites and applications will take a long time if you use outdated equipment like computers or laptops. That occurs as a result of the browser's inability to handle overload and its inability to complete tasks like DOM manipulation. Also, if you are unfamiliar with the framework, there may be some aspects that you misuse and end up spending hours on.
