Difference Between Angular and AngularJS

One distinction that JavaScript developers should be aware of is the distinction between Angular and AngularJS. This is because most of them, particularly newcomers, are perplexed as to how dissimilar these two frameworks are.


For quite some time now, Angular vs AngularJS has been a big topic of discussion, and it is likely to continue for many years to come. While both frameworks were created by Google, there are numerous differences between them. The primary distinction between AngularJS and Angular is that AngularJS is built with JavaScript, whereas Angular is built with TypeScript. There are significant similarities between these two open-source front-end frameworks for creating dynamic web applications and SPAs.




What is Angular?


Angular is an open-source web framework that is absolutely free to use. While it is a JS-based framework, TypeScript is its core programming language. TypeScript, developed by Microsoft, is a superset of JavaScript, which basically means that TypeScript has all of the capabilities of JS plus some more features. Angular is generally used to create fully featured web applications.


Angular was developed by Google and was originally made available to the public in September 2016. Angular's basic version is Version 2, while the most recent edition is Angular 12 or Version 12.


A well-known framework is an excellent choice for developing strong web apps with a modern design and highly dynamic behavior. Because Angular is modular, you may break the entire application into discrete portions (called modules) that represent a certain functionality. Angular allows you to easily create high-performance web applications while adhering to the MVC paradigm and providing two-way data binding.


Features of Angular


Angular is one of the most powerful JavaScript web frameworks available, owing to its extensive feature set. The best JS web framework enables the creation of modern, high-performance apps while also making the development process simpler. The following are the most notable Angular features that you should be aware of:


Cross-Platform: Angular allows you to design great user interfaces not only for online applications but also for native mobile and desktop applications. The framework is also useful if you want to create programs for the Windows, macOS, and Linux operating systems.


Makes Use of TypeScript: Angular uses TypeScript, which is superior to JavaScript because it is a statically-typed language. Because the types of variables are determined ahead of time, there will be fewer errors throughout the compilation process. Furthermore, any JavaScript code is valid TypeScript code. Furthermore, if you know JavaScript, learning TypeScript should be a breeze.


Angular CLI (Command Line Interface): Angular CLI is an excellent approach to accelerate development. There are various tasks that you can complete using Angular's native CLI, ranging from project setup to adding components and services.


Data Binding and Dependency Injection: The data binding functionality is what allows you to apply dynamic behavior to Angular-created web pages. Two-way data binding happens between the model and view components in general. Simply said, any changes you make to the view or UI elements will be reflected in the model or domain logic in real time. The opposite is also true.


On the other hand, the dependency injection functionality allows you to design entities that can deal with component dependencies. Services in Angular, for example, can execute tasks such as retrieving data from the server and applying validation rules to user input. These tasks can be made available to numerous components, and the process of making a service available to a component is referred to as dependency injection.


Advanced Animations: Complex animations are well supported by Angular. As a developer, you can simply add different animations to your application without having to write long code. Its specific functional API for animations makes it very easy to add animations to various portions of the UI.


Support for Unit Testing: With Angular, it is able to perform unit testing with relative ease, ensuring that your code contains few flaws. For rapid and easy debugging, the web framework makes use of the Karma test runner.


What is AngularJS?


AngularJS is a JavaScript framework that is open source and appropriate for front-end web development. AngularJS, which was also created by Google, is intended to make the building of single-page applications easier. [Instead of allowing a web server to load full new pages, SPAs (single-page apps) communicate with the user by dynamically modifying data from the web server].


One of the most notable features of AngularJS is that it is the first version of Angular. Simply mentioned, all 1. XX versions belong to AngularJS, which is also known as Angular 1. Version 2 and future versions, on the other hand, are referred to as Angular.


AngularJS was introduced by Google in 2010 and is written in JavaScript. Unlike Angular 2 and later versions, AngularJS does not use TypeScript.It is a significant difference between Angular and AngularJS.


The framework is well-known for its ability to create dynamic websites and online apps. Because it supports writing code in the MVC (Model-View-Controller) architecture, developers can add dynamic behavior to web applications. Furthermore, the architecture facilitates source code management and allows for rapid development.


Features of AngularJS


Prior to the release of Angular 2, AngularJS was widely utilized to build performant online apps. The reason for this is that AngularJS provides a wide range of functionalities that enable speedier development while also ensuring improved code maintainability. AngularJS has the following notable features:


Use of Plain JavaScript: AngularJS makes use of the JavaScript programming language, which has nothing to do with TypeScript. AngularJS models are also simple JavaScript objects because the framework uses plain JavaScript. This functionality makes it simple to test and manage AngularJS code.

Controllers and Directives: In AngularJS, directives and controllers allow you the authority to decide on functionality and have complete control over an application's behavior.


The controllers allow you to specify how DOM (Document Object Model) elements should behave. You can specify how DOM elements should behave in various situations. Directives, on the other hand, are directly put into the HTML code to integrate specialized functionality into the application. It's worth noting that controllers are created independently, whereas directives are utilized directly within (HTML) templates.


Components that are reusable: You can use AngularJS to construct reusable components that can be reused within an application. You will need to employ directives to create these components. A component can represent a specific function.


Routing: Routing is a feature that allows you to switch between different views of an application. Routing, in simple words, allows visitors to travel through different pages of a website or sections of a web app. Users can transition between multiple views in Angular single-page applications without having to reload the entire app or web page.
