If you’re involved in web development, there’s no doubt that you’ve heard about Angular JS by now. But if you haven’t started using it yet, then maybe you’re wondering why you should choose Angular JS over other frameworks and libraries out there. If so, then here are just some of the many benefits of Angular JS that will hopefully convince you to take the plunge and start using it. Read more Benefits of Angular js here.

There are hundreds of different frameworks to choose from, but Angular.js is one of our favourites—and for good reason. It’s a front-end framework (meaning it helps you create web pages) that was developed by Google and makes building scalable single-page applications easier than ever before. Plus, it has built-in features that help your app work faster, so users can get where they want to go more quickly. On top of all that, it’s totally free and open source!
MVC Architecture
MVC (Model-View-Controller) is a software architecture pattern that can be used to create reusable, maintainable code. In MVC, the Model represents data and its state. The view presents or displays data to the user. And Controller facilitates communication between model and view components by taking user actions and delivering the model’s response back to the view. Using MVC helps you cleanly separate business logic from your app’s front-end code. This makes it easier to build out new features and remove the complexity that would otherwise make your app difficult to update over time.
Data Binding
This is one of the more understated but incredibly powerful features in Angular. It allows you to bind data to views and have them automatically update when data changes (for example, adding a new item to an array). This means that if your view is displaying data from a model, you don't need to write any extra code to make sure that information stays up-to-date. As your model changes, it will automatically propagate updates all through your application. This helps with maintainability as well as performance—if your views and models are kept in sync, it's easier to make sure they're doing what they're supposed to do and nothing else.
Modules
Modular programming is a popular, tried-and-true development technique that eases code reuse, reduces repetition and helps simplify code maintenance. Until recently, though, it hasn’t been very popular in web development. That’s changing with frameworks like AngularJS. Designed as an open-source front-end framework by Google engineer Misko Hevery and his team, Angular was introduced in 2009.
Dependency Injection
A Dependency Injection is when a piece of software needs one or more objects in order to function properly. If those dependencies cannot be provided, then it’s an error and your application will fail to start. This can be quite problematic when writing client-side code because we typically want to keep our JavaScript as lean as possible. As such, AngularJS offers Dependency Injection out-of-the-box through a set of providers that are automatically configured at startup.
Routing
Because each web page is a separate, addressable unit, you can link directly to any section of your website. This means you can more easily manage complex websites with multiple pages and sections by using different URLs to point users to different areas. For example, if you own a large online store that has multiple product categories, then you could create several individual pages for those categories that all lead back to your main homepage (and still run on JavaScript). This allows easy navigation through your site while keeping everything under one address in terms of links and bookmarks. Some modern browsers will automatically process embedded JavaScript-based routing (this feature is called AJAX) so that when someone clicks on a hyperlink it fetches data from a server rather than loading an entirely new page.
Dependent Packages
With packages becoming more and more prevalent in front-end development, it’s important to note that you won’t be stuck using all of them. When using something like Bootstrap, a lot of developers tend to include its optional dependencies, even if they aren’t planning on actually using those libraries in their project. While these packages are downloaded during the build process when your package manager runs a command such as npm install or bower installs, you can always opt out by editing your .npmrc or .bowerrc file to ignore certain dependencies. This is especially important if you’re managing web server assets locally and don’t want unnecessary assets on your disk.
Separation of Concerns
One of AngularJS’s best features is its separation of concerns, meaning that front-end developers can spend their time on HTML, CSS and JavaScript without worrying about how it gets served up to users. With regular web development, a developer might have to create pages in PHP or ASP to get data from a database or serve up different types of content; with AngularJS, it’s all right there in JavaScript. Additionally, AngularJS lets you use directives to add functionality to your existing HTML structure rather than creating additional pages. This can make your website more user-friendly as well as easier to manage with SEO rankings in mind.
Testing Ease
In development environments, it’s not easy to create a page and test it quickly. But web applications need consistent tests that are always up-to-date with code changes. Fortunately, testing AngularJS is pretty easy! When you use Karma as your test runner and Jasmine as your testing framework, you can write tests directly in your HTML files. You can even convert these HTML files into automated tests! This makes testing easier and faster than ever before. It also helps prevent bugs, because automated tests run whenever someone commits code.
