Differences between Angular and AngularJS

Angular and AngularJS

Angular is a familiar framework for developing web applications for the vast majority of front-end developers. We discussed that Angular has undergone a major architectural overhaul and has rewritten the entire framework. Now, if we look back and try to make comparisons between the earlier AngularJS and today’s leading technology Angular, we see many important differences between the two. Ideally, if you are an Angular developer, or a front-end Angular developer in general, you should be aware of these differences as it is a great learning experience and a great addition to the knowledge base that not only covers the functional needs of the Technology, but also to reflect. on non-functional aspects, which also have a great influence. Below are some of the key differences between AngularJS (2010) and Angular 2+ (2016-present).

Angular Architecture  has an MVC (Model-View-Controller) architecture which is responsible for managing the data flow and logic, while Angular has a component-based distributed architecture.

Modularity – Most of the basic functionality was in one place in AngularJS, while Angular introduced the concept of distributed modules, which made the main module really lightweight.

Performance – The idea that Angular has a modular and distributed architecture is consistent with the fact that it is more power efficient than AngularJS.

The programming language is probably the most obvious difference; AngularJS uses JavaScript as its programming language, while the newer version of Angular has replaced it with TypeScript.

Angular Components – Angular uses components while the previous version of AngularJS had a directive-based approach.

Command Line Interface – Angular has its own command line interface that speeds up many application development processes. AngularJS, on the other hand, has no command line interface.

Dependency Injection – Angular takes as its primary approach an important design principle called Dependency Injection, which greatly improves runtime performance. AngularJS is not designed to inject runtime dependencies.

Mobile Browser – AngularJS does not support mobile browsers, while Angular 2+ has excellent mobile support.

Angular  versions

The following hierarchy gives a clear idea of ​​the different versions of Angular today.

Angular 1 – also called AngularJS, was released in 2010.

Angular 2 – A complete overhaul of the framework was officially released as Angular 2 in September 2016.

Angular 4 – Released March 2017.

Angular 5 was released seven months later than the previous version in November 2017.

Angular 6 – Released May 2018.

Angular 7 – Released the same year in October 2018.

Angular 8 – has a release date in May 2019.

Angular 9 – Released February 2020.

Winkel 10 – June 2020.

Winkel 11 – November 2020.

Comparison with other libraries and frameworks

Although Angular has the largest market share in the software industry, it is not the only front-end development environment. There are new ambitious players; Some are trying to enter the market, and some have already gained excellent recognition. Let’s take a quick look at the other technologies on the market and compare them briefly in the annular. There are two established JavaScript libraries that we can compare with Angular, namely Response and Vue. Both of them are well versed in the software industry and of course they work well even when they are designed. When it comes to the debate between Angular vs React and Angular vs Vue, the major differences between the two are as follows.

Components. When it comes to architecture, be it angular, reaction or view, components are very important. The only significant difference between the components in Angular and React or Vue is that the Angular components are very different and the logic within the components is completely independent of the presentation of the components. In Feedback and Vue, there is a user interface, so to speak, connected to the logic of the components, and therefore closely related to each other. This is the main advantage of Angular when we talk about Angular vs. React and Angular vs Vue. As far as, both approaches have their advantages and disadvantages, and it depends on the company they take.

Familiar with the framework. In the software industry it is often said that it is difficult to learn eGular in the beginning, but when the project develops, it is easier to navigate the project structure and then to adapt and learn. On the other hand, both Feedback and Vue are easy to start with, but later, because they are libraries, not frameworks, they are difficult to customize to project. By no means do we want to convey that we recommend for the mother to be inactive.

Size – Both are Responsive and Vue libraries and are therefore very light. When it comes to Angular, it is a bit heavy as a framework, but due to the minification, bundle and and package, the overhead can be greatly reduced. Here the debate has a slight edge between Angular vs. React and Angular vs Vue, React and Vue.

DOM manipulation. With the exception of a few edge cases, the Angular DOM tends to do a good job of manipulating.

Start time – When we talk about start time, it seems that Vue and React perform better than Angular because they are lighter. As mentioned, Angular One is a bit more cumbersome as a framework and therefore has a lighter impact on startup time.
