What is AngularJS?

AngularJS was an open-source JavaScript framework for developing single-page web applications. It is simply an extension of the DOM model, making the application more user-friendly and robust. It can be used, modified and shared by anyone. Currently, it is being maintained by Google. With AngularJS, developers can easily and comfortably maintain web infrastructures. Based on the MVC architecture, it is commonly used to build rich internet applications.

The AngularJS framework was built on the premise that declarative programming should be used to create user interfaces and connect software parts, while imperative programming should be used to define business logic.

 

Why AngularJS?

HTML is a great way to declare static documents, but it falls short when we try to declare dynamic views in web applications. We can extend HTML vocabulary with AngularJS. The resulting environment is exceptionally expressive, readable, and quick to develop.

  • AngularJS is a framework that was designed to create Rich Internet Applications (RIAs).
  • AngularJS gives developers the option to write client-side applications in JavaScript using a Model View Controller (MVC) approach.
  • AngularJS applications are cross-browser compatible. Each browser automatically handles JavaScript code.
  • AngularJS is open source, completely free and is used by thousands of developers around the world.

AngularJS is a framework that enables web developers to build large-scale, high-performance, and easy-to-maintain applications.

 

Extensibility

AngularJS is a toolset for building the framework most suited to our application development. The framework can be extended to work with other libraries. All features can be modified or replaced to suit your unique development workflow.

 

Features of AngularJS

There are many JavaScript frameworks available for developing web applications. The following are the features that make AngularJS one of the most powerful frameworks on the market:

  • Directives: A unique and powerful feature of AngularJS is its directives. With directives, we can create our HTML syntax.
  • Data Binding: In data-binding, the view is automatically updated whenever the model changes, as well as the model, is updated whenever the view changes. This is great since it eliminates the need to worry about DOM manipulation.
  • Controller: Controllers are responsible for the behaviour of DOM elements. A clean, readable form of behaviour is provided by AngularJS, instead of updating the DOM, registering callbacks or watching model changes.
  • Plain JavaScript: In contrast to other frameworks, accessor methods do not need to inherit from proprietary types. AngularJS models are just plain old JavaScript objects. As a result, our code is easier to test, maintain, reuse, and is free of boilerplate.
  • Localization: Localization is a key component of serious apps. With AngularJS’s locale-aware filters and stemming directives, we can build applications that work in all locales.
  • Deep Linking: A deep link indicates where the user is within the app. Users can bookmark and email links to locations within the app using this feature. Round trip apps receive this automatically, but AJAX apps by nature do not. AngularJS combines deep linking with desktop-like behaviour.
  • Injectable: AngularJS’ dependency injection feature makes it possible to declaratively describe your application’s wiring. Therefore, your application doesn’t require a (main) method, which is usually an unmaintainable mess. Dependency injection is also a core feature of AngularJS. As a result, any component that does not meet our requirements can easily be replaced.
  • Testable: AngularJS was designed from the ground up to be testable. The framework encourages behaviour-view separation, comes pre-bundled with mocks, and takes full advantage of dependency injection. AngularJS is also supported by an end-to-end scenario runner that eliminates test flakiness by understanding the inner workings of the framework.

 

Advantages of AngularJS

Following are the advantages of AngularJS, let’s discuss them one by one:

  • Open Source: Angularjs is an open-source JavaScript MVC framework, so anybody can create custom applications at an affordable cost. Since it is open-source, it provides the benefit of being able to easily change the source code to clarify things.
  • Built by Google: This is one of the greatest advantages of AngularJS. With a framework that is as robust and powerful as Google, we also have the advantage of getting the services of a broader community. We will be able to get what you want as a result of having a strong backing.
  • Single Page Application (SPA): A single page application means only a single HTML web page is loaded and further updates are made only to that one page. Because it is mainly used to create single-page applications and single-page applications are fast and easy to use.
  • No pre-requisite knowledge: Angular JS does not require any additional scripting language since HTML, CSS, and JavaScript is already working on it. Since HTML, CSS, and JavaScript are not hard to learn, we can easily learn Angular JS as well.
  • Easy to test: AngularJS supports both unit and integration testing. Because it is a JS framework, which involves dynamic coding everywhere, it requires high-end testing efficiencies. As a result, it contains powerful expressions but it doesn’t make use of the compiler, which is a drawback and requires effective coding across. However, integrating with dependency injection makes testing even easier.
  • Easy to extend and customize: It is easy to extend because of certain built-in attributes. By attaching specific behaviours to HTML attributes, the functionality of HTML can be extended. As a result, it can be customized with one’s directives too. Customized means adding or removing features or functionality to meet the specific requirements. The software is also user-friendly as it is purely according to the individual’s needs rather than including unnecessary elements.

 

AngularJS Disadvantages

These are the few disadvantages that one should be aware of:

  1. Less secure
  2. Not degradable.
  3. JavaScript support is mandatory.
  4. Not supported everywhere
  5. Memory leakage

 

Who can learn AngularJS?

AngularJS is a useful tool for anyone who wants to gain expertise in building SPAs (Single Page Applications) and rich client applications by consuming REST APIs. In addition, the skills of Web Developers, Project Managers, Software Architects, and Testing Professionals are also among the key benefits of AngularJS.

 

Career in AngularJS

By learning Angular, we will develop a comprehensive knowledge of Angular development as we pursue a career as a Front-End Developer, Software Engineer, Software Developer, etc. With the right skills, exposure, and hands-on approach, we will be able to specialize in particular areas from the start. The field of Web applications and Web development is expected to grow significantly in the coming year.
