Angular has passed various updates within a few years. The first version of Angular JS was developed by Google in 2009. After that, Angular has extended its versions, such as Angular JS 1.0, Angular 2.0, Angular 4, etc., to an extent to cater to the user base.
It is really difficult to choose which framework to generate dynamic web and mobile applications. Before jumping into the decision between Angular JS, Angular 2, and Angular 4, let’s take a look at them
Angular JS
Angular JS is a JavaScript-based framework which actively uses HTML as the template language. It is an open-source front-end web framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications
It is known for highly expressive and easy to read code structure, clean architecture and fast-paced development. Angular JS is one of the best single-page application development solutions.
Angular 2
Angular 2 is an open-source JavaScript framework to build web applications in HTML and JavaScript. Angular 2 was the first release in the Angular line-up after Angular JS. It introduced an altogether different programming approach compared to the Angular JS.
Angular 2 was reconstructed from scratch using TypeScript by the Angular team, via the concept of having components with better performance and improved features that would help Web Developers.
Angular 4
Angular 4 was released in March 2017 is nothing but an upgrade of the Angular 2 with several crucial value additions and major attractions and accommodation. It doesn’t come with any new approach to development but comes with a new library for HTTP requests and new events added to the router lifecycle.
Angular JS vs. Angular 2 vs. Angular 4
Architecture Basis
Angular JS- Angular JS architecture is based on the MVC (model-view-controller) design. The model is the central component that expresses the application’s response and manages its data, logic, and rules. The view generates an output based on the information in the model. The controller accepts input, converts it into commands and sends the commands to the model and the view.
Angular2- In Angular 2, controllers and scope were replaced by components and directives. Components are directives with a template. They deal with a view of the application and logic on the page. There are two kinds of directives in Angular 2.
Angular 4- In Angular 4, the structural derivatives ngIf and ngFor have been improved, and you can use if/else design syntax in your templates.
Language Basis
Angular JS- Angular JS is developed and written in JavaScript.
Angular 2- Angular 2 uses the typescript language of Microsoft which is basically a superset of ECMA script 6.
Angular 4- Angular 4 follows the most recent versions of TypeScript that have powerful type checking and object-oriented features.
Expression syntax Basis
Angular JS- Angular JS uses the suitable ng directive for combining the images with an event.
Angular 2- Angular 2 consider ‘()’ for an event and ‘[]’ for property binding.
Angular 4- Angular 4 follows the expression syntax in a different manner.
Mobile Support Basis
Angular JS- Angular JS was not built with mobile support in mind but other features support mobile.
Angular 2- Angular 2 helps you to develop a web app along with Cordova.
Angular 4- With Cordova update, Angular 4 also provides improved support like Angular 2.
Performance Basis
Angular JS- Angular JS was built for designers mainly not developers. Angular JS lacked many performances attributes that developers prefer. Angular JS helps to boost development speed, but for end-user or client-side, page speed gets slower.
Angular 2- Angular 2 in solves page speed issue through an easy and clean structure and a mechanism to detect changes.
Angular 4- As an upgraded version Angular 4 has come with more fine-tuned attributes to ensure faster development and client-side loading speed.
Final Words
Angular is getting better with every sub sequential upgrade. Every version of Angular has significant benefits, but there is much to gain in being up-to-date with the latest version. Now web app development has become more secure, easy, and quick with the help of Angular JS course in Noida and its upgraded versions.
