The contrast between Angular and AngularJS is one that JavaScript developers should be aware of. This is due to the fact that the majority of them, particularly beginners, are bewildered by how dissimilar these two frameworks are.
Angular vs AngularJS has been a hot topic for quite some time, and it is likely to remain for many years to come. While both frameworks were established by Google, they have significant distinctions. The main difference between AngularJS and Angular is that AngularJS is written in JavaScript, whereas Angular is written in TypeScript. These two open-source front-end frameworks for generating dynamic web apps and SPAs share many commonalities.
What is Angular?
Angular is an open-source web framework that can be used for free. It is a JS-based framework, but TypeScript is its primary programming language. TypeScript, created by Microsoft, is a superset of JavaScript, which means it has all of the capabilities of JS plus some extras. Angular is commonly used to build full-featured web applications.
Google created Angular and first made it available to the public in September 2016. Version 2 is the most basic version of Angular, while Version 12 is the most recent iteration.
A well-known framework is a fantastic alternative for creating robust web apps with a modern look and dynamic behavior. Because Angular is modular, you may divide the application into discrete sections (called modules) that each represents a specific functionality. Angular makes it simple to build high-performance web apps that adhere to the MVC paradigm and support two-way data binding.
Features of Angular
Because of its wide feature set, Angular is one of the most powerful JavaScript web frameworks accessible. The best JS web framework allows for the production of modern, high-performance apps while also simplifying the development process. The following are the most important Angular features to be aware of:
Cross-Platform: Angular helps you to create beautiful user interfaces not only for internet applications but also for native mobile and desktop apps. The framework is also suitable for developing applications for the Windows, macOS, and Linux operating systems.
Makes Use of TypeScript: Angular makes use of TypeScript, which is preferable to JavaScript because it is a statically-typed language. There will be fewer errors throughout the compilation process because the types of variables are established ahead of time. Furthermore, TypeScript code is valid for any JavaScript code. Furthermore, if you’re already familiar with JavaScript, learning TypeScript should be a breeze.
Angular CLI (Command Line Interface): Angular CLI is a great way to speed up development. You may use Angular’s native CLI to execute a variety of tasks, from project setup to adding components and services.
Data Binding and Dependency Injection: Data binding allows you to apply dynamic behavior to Angular-created web pages. In general, two-way data binding occurs between the model and view components. Simply said, any changes you make to the view or UI elements will be reflected in real-time in the model or domain logic. The inverse is also true.
The dependency injection mechanism, on the other hand, enables you to create entities that can deal with component dependencies. Angular services, for example, can perform tasks such as fetching data from a server and applying validation rules to user input. These tasks can be made available to a wide range of components, and the process of making a service available to a component is known as dependency injection.
Complex Animations: Angular supports complex animations nicely. As a developer, you can easily add various animations to your application without having to write lengthy code. Its animation-specific functional API makes it very simple to apply animations to various parts of the UI.
Support for Unit Testing: Angular allows for very simple unit testing, guaranteeing that your code is free of bugs. The web framework takes use of the Karma test runner for quick and easy troubleshooting.
What is AngularJS?
AngularJS is an open-source JavaScript framework designed for front-end web development. AngularJS, which was also created by Google, is meant to simplify the development of single-page applications. [Rather than allowing a web server to load completely new pages, SPAs (single-page apps) connect with the user by dynamically altering data from the web server.]
The fact that AngularJS is the original version of Angular is one of its most prominent aspects. Simply put, all 1. XX versions are part of AngularJS, often known as Angular 1. Version 2 and subsequent versions, on the other hand, are known as Angular.
Google introduced AngularJS in 2010 and it is built in JavaScript. AngularJS, unlike Angular 2 and later versions, does not use TypeScript. There is a significant distinction between Angular and AngularJS.
The framework’s ability to develop dynamic websites and online apps are well-known. Developers may add dynamic behaviour to web applications since it supports writing code in the MVC (Model-View-Controller) architecture. In addition, the architecture simplifies source code management and enables rapid development.
Features of AngularJS
Prior to the release of Angular 2, AngularJS was widely used to create high-performance web applications. This is because AngularJS offers a wide range of functions that allow for faster development while also providing enhanced code maintainability. AngularJS contains the following significant characteristics:
Plain JavaScript is used: AngularJS employs the JavaScript programming language, which has nothing to do with TypeScript. Because the framework is written in plain JavaScript, AngularJS models are similarly simple JavaScript objects. This feature simplifies the testing and management of AngularJS code.
Controllers and Directives: In AngularJS, directives, and controllers provide you the authority to decide on functionality and complete control over the behavior of an application.
You can use controllers to indicate how DOM (Document Object Model) elements should behave. You may tell DOM elements how to behave in certain situations. Directives, on the other hand, are directly inserted into HTML code to incorporate specialized functionality into the program. It should be noted that controllers are created independently, whereas directives are directly used within (HTML) templates.
Reusable components: AngularJS may be used to create reusable components that can be reused inside an application. To create these components, you will need to use directives. A component can stand in for a specific function.
Routing: Routing is a feature that allows you to navigate between multiple views of an application. In layman’s terms, routing allows visitors to navigate through different pages of a website or sections of a web app. Users with Angular single-page applications can switch between various views without having to restart the entire app or web page.
