Angular 2 vs React — What Developers Often Forget?
One of the most common comments we heard from many AngularJS developers in 2015 was perhaps, “ I had a great time working with AngularJS 1, but I am shifting to React now”. The alpha version of Angular2 has been made accessible to programmers much earlier in this year, and the improved beta version is still on the wait. Even before the launch of Angular 2, a tug of war has been initiated between AngularJS developers and React developers. This resulted in the writing of many biased articles and blogs that highlight React as a winner by forgetting the essential merits of Angular. The article puts forward an impersonal view of the vital facets endorsed by both these illustrious platforms.
Note:- Many developers consider comparing Angular 2 with React is senseless, for Angular is a framework and React is a library. However, those who compare these two technologies are not doing an inexpiable crime, for both are front-end UI designing technologies that work with different approaches. This extract is not a hardcore comparison to trace out the “clear winner”by analyzing all those hair-splitting arguments, but it attempts to highlight certain key aspects that developers often ignore at the time of making partial promotions.
The main objective of React is to provide developers with an excellent view for their application and to offer effective ways for the framing of reusable declarative plugins.
Angular 2 Objective
Angular 2 aims to offer programmers a complete front-end framework which reinforces a fine dissolution of concerns instead of sticking to a particular architecture.
React and Angular 2 — Similarities
Both React and Angular 2 serve developers as front-end technologies that assist them to detail the view of the web or mobile applications, and component based UI. These technologies are crafted to function with FRP & OOP paradigms without any performance lags.
React and Angular 2 — Differences
Angular 2 is a fully developed framework and React is a library having additional libraries backed by the communities. Angular 2 offers more functionality. The change detection is entirely different on both these platforms. Angular 2 comes with an enforced separation of concerns in dependency injections, and services. DI manages Inversion of controls in Angular 2. The language used in Angular 2 is TypeScript, and React runs on ES5/ES6. Both support different ways to define the UI, Angular 2 uses HTML templates and React makes use of JSX. React supports static typing which helps it to gain a little performance improvement over Angular 2. React enables virtual DOM differentiating and Angular 2 makes use of tedious checking.
Merits and Demerits of React
Programmers can implement two separate methods. They can deal with data changes(component update) only or permit React to count on the alterations automatically. In React batches changes altogether, and it is a much easier technology to learn. The flux like architecture brings in improved performance while dealing with DOM.
One of the major demerits of React occurs while implementing the change detection. This process lacks extensibility. Stack traces in React are a bit confusing.
Merits and Demerits of Angular 2
A major advantage programmers receive by using Angular 2 is in dealing with change detection. It offers options to develop change detection for the complete application as well. Separate algorithms are available for speedy incline caching and dynamic change detection.
Learning curve of Angular 2 is low, hence novice developers find greater difficulty in learning the syntax and structure. Performance, error messages, and tooling lag a little behind in comparison to React.
Where can React be used on contrary to Angular 2?
React contains libraries that most developers are familiar with, hence developers can integrate libraries in the project much easily. jQuery applications can be quickly migrated to React. React offers better IE8 support, and remains as a highly matured technology. The functioning of synthetic events is simply superb while dealing with SVG.
Where Angular 2 can be used on contrary to React?
Angular 2 is modern and built-in by keeping higher standards in mind. It offers a tremendous backing for web components, joining of projects, and web artisans. Angular 2 is well- arranged with convenient change detection options, and similar practices (once mastered it is easy to use).
Key Aspects of Angular 2 and React
- Both Angular 2 and React allows “Hot reloading” in different ways for Angular follows TS which offers a prototype for the hot loader and React’s flux-like structure offers a mature hot loading.
- When it comes to server-side rendering React offers a much more mature handling, but Angular 2 stays ahead in performance.
- In JSX (React) developers do not have to learn any additional syntax but to use Angular 2 developers will have to learn particular syntax( best cases in point are events and properties).
- Angular 2 templates are fully declarative. A single component can utilize multiple templates, hence it supports easy reuse of codes, especially with different views.
- React backs nullable and is so simple to integrate. On the other hand, Angular 2 comes with a superb text editor, typed definitions, and a backing for interfaces.
- React offers better support for both iOS and Android mobile solutions whereas Angular 2 is largely NativeScript.
- Angular templates pack JS in HTML and React(JSX) covers some HTML in JS.
- The library of Angular is so extensive, but React offers a micro library which is effective and more purposeful.
- Tooling in React is superior to Angular 2.
- Angular 2 file size is bigger than React, but it will get reduced when the beta version gets launched(high probability).
- Error messages and tooling will be much better in Angular 2 Beta.
- We can expect an Angular 2 Beta which is more Java based like React.
- Angular 2 scales a bit better than React on server-side rendering for the plugins get loaded asynchronously. In React, programmers will have to mention “shouldComponentUpdate” to avoid the call blocking. It helps Angular 2 views to load quickly.
- React has more new ideas like clojure, redux, +om so on.
Bringing It Altogether
React and Angular 2 are great technologies. The tug of war is so closely tight and predicting a clear winner is really hard. The choice between the two in most occasions may dependent upon the comfort, technical know-how, and productivity of developers.
