Angular is a mode or platform which makes it easy for building applications with the help of the web. This combines declarative templates, dependency injection, end-to-end tooling, and various integrated best methods for solving development challenges. Professionals who have been working in the development domain for almost a decade have observed different types of Angular versions. Even the same is the case with front-end technologies. In the past, HTML and CSS dominated the industry. With no good skill in Angular JS has landed a good job as a front-end developer.
The demand for developers who are skilled in Angular has increased in different folds. Various technologies have enabled the internet to change, progress, and evolve at a rapid rate. Angular is a case in point with wide change in just a few years. Google further developed AngularJS in 2009, and version 1.0 was released in 2012. Angular has further dominated the world of open-source JavaScript frameworks with increased support and widespread adoption. Further, angular has evolved from Angular JS version 1.0 to Angular version 2.0 and then the latest Angular version 4.0 all in five years. The angular community has different concerns about moving to a new version. Let us get into insight about the different types of angular versions:
Angular
This is an open-source, JavaScript framework that is written in TypeScript. Google maintains this and even offers standard structures for developers to work with. Angular make use of HTML syntax for defining the various components of the program in a well-defined manner. This enables developers to build large applications in a maintainable way. Angular is a big term that is used for all versions that came after AngularJS (Angular 1), i.e., Angular 2, Angular 4, Angular 5, and now Angular 6. This has the latest and most refined framework to date for designing a web application that is dynamic and responsive. With the help of HTML as a template language, this has created an environment that is quick to develop and more easily readable. This lets developers create more reusable codes. Thus, this has less to do with coding, and this saves time and helps one to increase efficiency greatly.
Angular JS
AngularJS is an open-source front-end web framework that is based on JavaScript for building dynamic web applications. This allows the developer to use HTML as a template language and extend the syntax for creating various application components. This was created by Misko Heavery and he has built a framework for handling the downfall of HTML and also takes ideas and practices of libraries which are never done. Some features of AngularJS are a JavaScript MVW Framework, extended HTML support involving the use of tags, attributes, and expressions, allowing easy event handling, support for data binding, a built-in template engine, and routing and dependencies injection.
Angular 2
This is an AngularJS version built around various concepts of components, and this allows one to build JavaScript classes. After AngularJS, Angular 2 is a complete rewrite of the original Angular 1 or AngularJS. Some important features include a modern, faster, and highly scalable framework, an equally useful framework for web, desktop applications, web applications, web components based architecture, and even supports hierarchical dependency injection.
Angular 4
This is a web application framework for building JavaScript apps. This supports TypeScipt together with JavaScript and displays the same. This provides a navigation toolbar, auto-complete, menus, and many more. This is unlike Angular 2, which is a written version of Angular 1. Some features of this include reducing the size of generated bundled code up to 60%, animation moved out to a different package, support for if/else statement, and support for email validator.
Angular 5
This is also an open-source web application framework that is based on TypeScript. Many advanced features have been added to the improvement, such as dependency injection, declarative template, end-to-end tooling, etc. This does not bring any significant changes in comparison to Angular 4. Features of this involve making AOT the default, easier to create a progressive web app, type checking in the template, support for internationalized number, date, and currency pipes, updating to Httpclient, and new router lifecycle events.
Angular 6
This was released in April 2018, and this focuses less on the underlying framework and more on the toolchain, and this makes it easy to move quickly with Angular in the future. There are no major breaking changes, and this has a dependency on RxJS 6. This has the features of the angular framework, angular CLI, and Angular Material +CDK. These are all features of now version 6.0.0; minor and patch releases, though they are independent and are changed on the basis of a specific project.
Angular 7
This is an open-source JavaScript framework for building web applications and apps in JavaScript, HTML, and Typescript, a subset of JavaScript. This provides built-in features for animation, HTTP service, and material for complete navigation, toolbar, menus, etc. This is one of the most widely used languages, and the use involves google supported community, POJO-based development, declarative user interface, typescript, modular structure, multi-platform support, etc. The new Angular 7 features include Angular material, CDK, Performance improvement, and CLI prompts. This has made things easy and quick for building applications, and this has made the life of developers more reliable and filled with relief.
Angular 8
This was released in May 2019. Features of this have differential loading by default, a process by which the browser chooses between modern or legacy. In this, builder APIs in CLI is an exciting feature using customizing angular CLI commands.

Angular 9
This was released in Feb 2020. Important features include Ivy compiler-a from version 9, all applications have been shifted to Ivy compiler and runtime by default, and this provides advantages such as smaller bundle size, faster testing, better debugging, improved CSS class and style binding, and improved type checking, improved build errors, etc.
Angular 10
This was released in June 2020. This release has a small change in comparison to other releases. Important features include a date range picker and a warning about Common JS imports.
Angular 11
This was released in Nov 2020. This helps in popular bug fixes such as router link and i18n. Important features include automatic font inlining with improved build and serve reporting and logging and updated language service based on Ivy.
Angular 12
This was released in May 2021. This feature includes passing context to HTTP interceptors and also supports inline Sass in style property.
Angular 13
This was released in Nov 2021. This continued moving forward with Ivy. important features include creating dynamic components has become easy, and IE 11 support is removed.
Conclusion
As you have observed that Angular is constantly growing with better features and unique performances. Many upcoming versions are coming, such as Ivy renderer and Bazel which are used for optimum previews.
