1. What is Angular?
Angular is a web application development framework built and maintained by Google, written in TypeScript. Angular is part of the JavaScript platform for building single-page web applications (Single Page Applications – SPAs).
Angular provides a component-based approach, where each component represents a part of the user interface and it can contain its JavaScript, HTML, and CSS code. These components can interact with each other through services, and the entire application is managed through a virtual database called the “application graph”.
Angular provides a variety of features such as two-way data binding, dependency injection, routing, and many other development tools that make building web applications easier and more efficient. more effective.
2. Angular development process
- AngularJS (2010): AngularJS was developed by Misko Hevery and Adam Abrons at Google. AngularJS is a JavaScript framework that Google developed to help build dynamic, single-page web applications (Single Page Applications – SPAs).
- Angular 2 (2016): After a period of development and learning from experience with AngularJS, Angular 2 (commonly known as Angular) was introduced in September 2016. Angular 2 is not just an updated version of AngularJS but also a completely new version with a different architecture and syntax. Angular 2 is completely rewritten in TypeScript and has many improvements in performance, testability, and module system.
- Angular 4, 5, 6,… (2017-2018): Angular continues to update with new versions. These versions often bring performance improvements, features, and bug fixes. Angular uses a regular release cycle and ensures backward compatibility with previous versions.
- Angular 7, 8, 9,… (2018-2019): As with previous versions, new versions of Angular continue to bring improvements in performance, features, and bug fixes. Angular also focuses on optimizing the size of the application and improving the development experience.
- Angular 10, 11, 12,… (2020-2021): New versions of Angular continue to introduce improvements and new features, as well as bug fixes. Google and the Angular developer community both contribute to the maintenance and development of the framework.
- Angular 13: Deep integrations, performance, and security make Angular 13 an important step forward.
3. Basic features of Angular
- Component-Based: Angular uses a component architecture, where each part of the application is represented as an independent component. Components are user interface building blocks and contain their own JavaScript, HTML, and CSS code.
- Two-Way Data Binding: Angular supports two-way data binding, allowing automatic synchronization between data and the user interface. Changes in data will immediately reflect on the interface and vice versa.
- Dependency Injection: Angular uses a Dependency Injection (DI) system to manage and organize application components. This reduces code complexity and creates code that is easy to test and reuse.
- Routing: Angular provides a built-in routing system that allows switching between pages and components in the application without reloading the page.
- Forms: Angular provides a powerful module to manage and process forms. This includes user control, data validation, and user interaction.
- Modules: Angular applications are organized into modules, helping to manage the source code and functions of the application in an organized way.
- TypeScript: Angular officially uses TypeScript, a superset of JavaScript with static data types and many other features, which help control errors, improve performance, and make code more readable and efficient.
4. Are Angular and AngularJs the same?
Angular and AngularJS are two web application development frameworks from Google, and they have important differences in architecture, syntax, and features. Some key differences between AngularJS (commonly known as Angular 1.x) and Angular (commonly known as Angular 2 onwards).
- Architecture and language:
- AngularJS: Uses JavaScript or an improved version of it called TypeScript.
- Angular: Officially uses TypeScript, a superset of JavaScript with static data types and many other features.
- Ingredients and directives:
- AngularJS: Use ng-controller, ng-model, ng-repeat and other directives to create and manage components in the application.
- Angular: Use components and directives to create application structure. There is a component-based architecture model.
- Dependency Injection:
- AngularJS: Does support Dependency Injection but is not a major part of the framework.
- Angular: Uses Dependency Injection which is powerful and is an important part of how Angular manages and organizes source code.
- Routing:
- AngularJS: Has routing but not built-in, often requires using additional modules like ngRoute.
- Angular: Has a built-in routing system, helping to conveniently manage and navigate between pages.
Due to the huge difference between AngularJS and Angular, people usually do not switch directly from one framework to another but instead often rebuild the application from scratch when wanting to switch from AngularJS to Angular.
5. Should I learn Angular or AngularJs?
Deciding whether to learn Angular or AngularJS depends on your specific goals and context.
- AngularJS: Learn if you are working on a legacy project using AngularJS or want to understand the history and origins of Angular.
- Angular: A good choice if you’re just starting out or want to update your knowledge with a modern, continuously supported and developed framework.
