AngularJS is a JavaScript MVC framework for developing single-page, dynamic web applications. When we say an application is dynamic, we mean that the data and information used and displayed in the application can change automatically without the need for developer-managed editing or updating. Google manages the AngularJS framework as an open-source project. It maintains a robust list of features from which developers can pick and choose, and it does not impose a specific file structure or code organization on you.
To better comprehend the significance of this, let's examine the origins of the Internet.
In the beginning, HTML was used to create static documents with hyperlinks that allowed for navigation between them. Primarily, these would have been academic documents with headings, paragraphs, and tables containing scientific data.
With the development of the Common Gateway Interface (CGI) in 1993, however, it became possible to display dynamic content generated by server-side applications. Perl was one of the first languages used for this purpose, followed by languages/platforms including Java, ASP.NET, PHP, Ruby, ColdFusion, and Python. It was difficult to experience the same level of interaction as desktop applications when interacting with complex applications through a browser.
The goal of web development has always been to create an interactive user experience comparable to desktop applications. However, technology continued to advance, initially with plugin-based technologies such as Flash, Flex, and Silverlight.
Simultaneously, the new versions of JavaScript, HTML, and CSS were rapidly gaining popularity, thereby transforming the future of the web by achieving a high level of user experience without the use of proprietary plugins.
This was satisfactory. Steve Jobs announced in 2012 that Apple would no longer support Flash-based applications on any of its devices due to security concerns and Flash's propensity to cause Safari to crash.
Within a matter of months, programmers all over the world began searching for alternatives that could provide a similarly rich experience to what they had just lost. These plugins were no longer necessary due to advancements in CSS, Javascript libraries like JQuery, and the introduction of HTML5. And with browsers essentially displaying content in the same manner from 2010 onwards, a number of clever and inventive individuals began creating more libraries and frameworks that offered a dynamic web experience through the use of patterns that made the lives of developers a little easier.
In October 2010, AngularJS joined the new generation of libraries and frameworks that facilitate the creation of more efficient, flexible, maintainable, and testable web applications.
AngularJS is an open-source JavaScript client-side framework that promotes highly productive web development. It was developed on the premise that declarative programming is the best option for constructing an application's user interface, whereas imperative programming is far superior for implementing an application's business logic.
To accomplish this, AngularJS bolsters traditional HTML by extending its existing vocabulary, making the lives of developers easier. The end result is the creation of expressive, reusable, and maintainable application components, leaving behind a significant amount of unnecessary code and allowing the team to remain focused on valuable and essential tasks.
When visiting and using web applications, we now anticipate a visual and interactive experience. We anticipate that dynamic content will appear frequently on our screens without requiring us to refresh our browsers. AngularJS is one framework that enables developers to create this end-user experience. And through the use of an MVC-based pattern, developers are able to construct applications rapidly and, just as importantly, maintain them without difficulty.
There are other frameworks available, such as React, in addition to AngularJS. ReactJS is described in the following section.
Node JS is ideal for rapidly developing scalable back-end networking applications, whereas AngularJS is designed for single-page front-end applications. The following is information about NodeJS.
VueJS is reportedly simpler to learn than Angular due to its HTML-based syntax. The following is information about VueJS.
