Comparison between React and Angular 2

Angular and React, both are fabulous JavaScript UI frameworks that have made developing quality applications with intended interface designs a breeze. While Angular.js is an app development framework that is available around for some time now, React.js is just an interface development framework, which is not that old. Although Angular.js offers excellent features, React.js with amazing rendering performance has proved to be a much sought after choice for many projects. In this article we will focus on unique features of each Angular 2 and React respectively followed by a comparison chart.

Unique features of Angular 2

  • Typescript: Typescript is developed by Microsoft and is the type superset of JavaScript that compiles your code into plain JavaScript. Typescript can easily track the bugs in your code as it offers you a complete set of features for advanced IntelliSense experience for programmers.
  • Dependency Injection - Dependency injection is an important application design pattern. Angular has its own dependency injection framework, and you really can't build an Angular application without it. It's used so widely that almost everyone just calls it DI.

Dependency injection is the ability to add the functionality of components at runtime. Thus, If requested service is not in the container, Angular inject will auto-create and inject into your component.

  • Jasmine - The Jasmine test framework provides everything needed to write basic tests. It ships with an HTML test runner that executes tests in the browser.  It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.

Unique features of React:

  • One way Data flow - React.js is designed in such a manner that it will only support data that is flowing downstream, in one flow. If the data has to flow in another direction, you will need additional features. The reason behind this is because components are supposed to be immutable and the data within them unable to change. This way, they will only listen to data that is flowing from upstream and not data that is coming from each other. That is why React.js is known for the creation of canonical data sources that will stay synchronized across the components that will pay attention to it. It is what makes it the best framework for creating highly interactive web applications

 

  • React.js is extremely efficient: React.js creates its own virtual DOM where your components actually live. This approach gives you enormous flexibility and amazing gain in performance. React.js also calculates what are the changes needed to be made in DOM. This process of React.js avoids expensive DOM operations and makes updates in a very efficient manner.

 

  • It makes writing JavaScript easier: React.js uses a special syntax called JSX, which allows you to mix HTML with JavaScript. The user can drop a bit of HTML in the render function without having to concatenate strings, this is another fantastic thing. React.js turns those bits of HTML into functions with a special JSXTransformer.
