Angular Version List and History

Let’s see the Angular version history in details:

History of Angular 1

History of Angular 2

Angular 2 is a fully built and completed rework version from Angular 1. It is compatible with mobile devices. Moreover, Angular 2 gives you an option to choose more languages where you can choose your language like ES5, ES6, or TypeScript to write the codes of Angular 2.

History of Angular 4

As discussed earlier, Angular 3 was not released by the Angular team. Angular 4 was released on March 6, 2017, which is compatible with most of the applications. However, there is not any major changes in Angular 4 from Angular 2, and it offers better bug fixed, and alerts compare to Angular 2.

Angular Elements, Component Dev Kit, Angular Material Starter Components, Library support, and Tree Shakeable Providers are some new features added in this version.

History of Angular 7

Angular version 7 was released on October 18, 2018. Updates regarding Application Performance, CDK, Angular Material Virtual Scrolling, It also provides Improved Accessibility of Selects, support for Content Projection using web standard for custom elements, and dependency updates regarding Typescript 3.1, RxJS 6.3, and Node 10.

History of Angular 8

Angular version 8 was released on May 28, 2019. This update enhance loading for all application codes, Web worker’s Dynamic imports for lazy routes. It also supported TypeScript 3.4, and Angular Ivy as an opt-in preview.

AngularJS was created by Misko Heavery. He had built a framework to handle the downfalls of HTML and also taking ideas and best practices of the libraries which were never done earlier.

This first version of the framework known as AngularJS was launched in the year 2009. It laid the foundation of the present-day front-end application development. Angular JS was one of the best single-page application development solution. Gradually, it wide adoption and become very popular.

Features of Angular JS

• A JavaScript MVW Framework
• Extends HTML support by adding tags, attributes, and expressions
• Allows easy event Handling
• Supports for Data Binding
• Built-In Template Engine and Routing
• Form Validations and Animations
• Dependencies Injection

Some Important Features of Angular 2 are:

• Modern, faster, and highly scalable framework
• Equally useful framework for web, mobile, and desktop apps
• Web components based architecture
• Supports Hierarchical Dependency Injection

Why not Angular 3?

Angular 2 has been a single repository. Each package downloadable with the @angular/package-name convention. For example @angular/HTTP, @angular/router

All package names were assigned version 2, but router package by mistaken was given version 3. Therefore, the development team skipped Angular Version 3 and directly named it version 4 to maintain compatibility with Angular Router’s version.

Some other features of Angular 4 are:

• Reduce the size of the generated bundled code up to 60%
• Animation moved out to a separated package @angular/animations
• Supports for if/else statement
• Supports for email validator

Features of Angular 5:

• Make AOT the default
• Easier to build progressive web apps
• Type checking in templates
• Support for Internationalized Number, Date, and Currency Pipes
• An update to Httpclient
• Zone speed improvements
• New Router Lifecycle Events

Difference between AngularJS and Angular 2

Below is a main difference between AngularJS Vs Angular 2:

Angular JS	Angular 2
Released by Google in the year 2010.	Released in Sept 2016.
JavaScript-based framework for creating SPA.	Complete re-write of AngularJS version.
Still supported but no longer will be developed.	It’s updated version regularly released because of Semantic Versioning.
The architecture of AngularJS is based on MVC.	The architecture of Angular 2 is based on service/controller.
AngularJS was not developed with a mobile base in mind.	Angular 2 is a mobile-oriented framework.
AngularJS code can write by using only ES5, ES6, and Dart.	We can use ES5, ES6, Typescript to write an Angular 2 code.
Based on controllers whose scope is now over.	Nowadays, the controllers are replaced by components, and Angular two is completely component based.
Factory, service, provider, value and constant are used for services	The class is the only method to define services in Angular2
Run on only client-side	Runs on client-side & server-side
ng-app and angular bootstrap function are used to initialize	bootstrapmodule() function is used to initialize

Difference between Angular 2 and Angular 4

Following is the key difference between Angular 2 Vs Angular 4:

Angular 2	Angular 4
The code generated using Angular 2 is bigger, and the file size is also larger.	Angular 4.0 has reduced the bundled file size by 60%. Thus code generated is reduced which helps to accelerate the application performance.
Angular two is not backward compatible with Angular JS.	Angular four is backward compatible with Angular 2 for most applications.
There is no specific no proper disapproval phases to adjust codes.	There will be proper disapproval phases to allow developers to adjust their code
There is no animation feature offers in Angular 2.	Animation features are pulled out of @angular/core and included into their package

Difference between Angular 4 and Angular 5

Here is the difference between Angular 4 Vs Angular 5:

Angular 4	Angular 5
Support for Router ParamMap	New Router Lifecycle Event
Dynamic Components with NgComponentOutlet	Compiler Improvements
TypeScript 2.4 with this version that functions as a JavaScript superset that can be used for optional static typing, interfaces, and classes	Angular 5 comes with build optimizer which is a part of the platform’s command like a tool.
HTTP Request Simplified	Optimization with HttpClient Feature
Includes Animation Package	Internationalized Date & Currency

• All package names were assigned version 2, but router package by mistaken was given version 3. Therefore, the development team skipped Angular Version 3 and directly named it version 4 to maintain compatibility with Angular Router’s version.
• Angular 4 is a web application framework for building JavaScript applications. It supports TypeScript, which compiles to JavaScript and displays the same in the browser.
• Angular 5 is an open-source web application framework which is based on TypeScript. There are lots of new features and improvements done in this version like dependency injection, declarative templates, end-to-end tooling, etc.
