One of the most popular and frequently used front-end development frameworks is Angular. The market for recruiting Angular engineers has gotten more competitive as the popularity of this technology has grown. As the demand for professional and experienced Angular programmers grows, more countries are looking to expand their Angular development workforce. Mobile and desktop applications can be built using this platform. Angular is used by a number of cutting-edge organizations to construct modern web applications.
However, if you are still unaware of this technology, here is a complete Angular 8 Tutorial that will help you learn Angular 8 from scratch.

History & Versions
Angular was rewritten from the ground up of AngularJS by Google.
Angular 2
Angular 2.0 was announced in October 2014. The dramatic modifications in version 2.0 sparked a lot of debate among developers. Angular 2 was promoted from Alpha to Developer Preview on April 30, 2015, according to the Angular team. In December 2015, Angular 2 was promoted to Beta, and the first release candidate was released in May 2016.
Angular 4
On 13 December 2016 Angular 4 was announced,and 3 is skipped to avoid confusion caused by a version mismatch in the router package, which was already published as v3.3.0. HttpClient, a simpler, easier-to-use, and more powerful library for making HTTP Requests, as well as router life cycle events for Guards and Resolvers, were introduced in this release.
Angular 5
Angular 5 was released on November 1, 2017. Support for progressive web apps, a build optimizer, and Material Design improvements are among the highlights of Angular 5.
Angular 6
Angular 6 was released on May 4, 2018. This is a big version that focuses less on the underlying framework and more on the toolchain and making future Angular development easier, like: ng update, ng add, Angular Elements, Angular Material + CDK Components, Angular Material Starter Components, CLI Workspaces, Library Support, Tree Shakable Providers, Animations Performance Improvements, and RxJS v6.
Angular 7
Angular 7 was released on October 18, 2018.Updates to Application Performance, Angular Material & CDK, Virtual Scrolling, Improved Accessibility of Selects, Content Projection utilising web standards now supported for custom elements, and Typescript 3.1, RxJS 6.3, and Node 10 dependency updates(still supporting Node 8)
Angular 8
Angular 8 was released on May 28, 2019. Differential loading is available for entire application code, as well as dynamic imports for lazy routes, Web workers, TypeScript 3.4 support, and an opt-in preview of Angular Ivy. The opt-in preview for Angular Ivy contains:
- Code generated that is easier to read and debug at runtime
- Faster rebuild time
- Improved payload size
- Improved template type checking
- Backwards compatibility
Angular 9
Angular 9 was released on February 6, 2020. By default, all applications in Version 9 use the Ivy compiler and runtime. Angular can support TypeScript 3.6 and 3.7.
The Ivy compiler and runtime, in addition to hundreds of bug fixes, provides a number of benefits, such as:
- Smaller bundle sizes
- Faster testing
- Better debugging
- Improved CSS class and style binding
- Improved type checking
- Improved build errors
- Build times have been improved, and AOT is now enabled by default.
- Improved Internationalization
Angular 10
Angular 10 was released in June, 2020.
- New Date Range Picker (Material UI library)
- Warnings about CommonJS imports
- Optional Stricter Settings
Keeping Up to Date with the Ecosystem
New Default Browser Configuration
Angular 11
Angular 11 was released in November 2020.
Angular 12
Angular 12 was released in May, 2021.[25]
Deprecated support for IE11
Each version should be backwards compatible with the previous release.
The Angular development team has committed to updating the framework twice a year.
What is Angular?
Angular is a Typescript-based open-source framework for building client-side web applications. Since Typescript is a superset of JavaScript, let us first understand JavaScript briefly. JavaScript runs on the client-side of the web, which can be used to design or program how the web pages behave on the occurrence of an event. Typically, JavaScript is used for interface interactions, slideshows, and other interactive components. JavaScript evolved quickly and has also been used for server-side programming (like in Node.js), game development, etc.
JavaScript deals with dynamic content, which is an important aspect of web development. Dynamic content refers to constantly changing content and it adapts to specific users. For example, JavaScript can be used to determine whether or not to render the mobile version of the website by checking the device, which is accessing the website.
This encouraged web developers to start creating their own custom JavaScript libraries for reducing the number of code lines and implementing complex functionalities easily. jQuery is a fast, small, and feature-rich JavaScript library, which makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API. jQuery became the most popular one because it was easy to use and extremely powerful.
