However, sometimes it is very difficult to do. That’s today we decided to compare two extremely popular frontend technologies to understand which one is better to use and when.understand which one is better to use and when.

Let’s start with Angular 2. It is a Javascript framework with open source, that is way much better than the first Angular. The main difference is a simplification, which means that you won’t find here all those complicated modules and directives that made Angular 1 so complicated and agglomerate. The result was immediate and the performance of the technology increased greatly. Along with that, now the technology supports native app and can render on a server side.

The technology gained its popularity due to the name of its creator (Google), more than that, the framework is very easy to learn.

Yet, just like every tool, this one has its advantages and disadvantages as well. Among the assets we can list:

  • Orientation on the apps with a big amount of interactive client-side code.
  • Good solution for dynamic apps with a single page.
  • Fast development process
  • Needs less code in some classes
  • Advanced testing features
  • Model-View-Controller balance

Lower we listed the disadvantages of the framework:

  • Relatively slow when it needs to display large amounts of data
  • Not very SEO friendly.

React JS is a library that also has open source and includes JSX compiler. The fundamental contrast of these systems is that React JS is a library to render your views, not a framework. It became popular because of the Facebook, that backs it up. React JS is a rather SEO friendly technology. And the icing on a case is its high performance and flexibility.

The pros of the technology are:

  • It’s very compatible with SEO principles
  • UI text cases are easy to create
  • You can reuse the components easily
  • Fast with big number of elements
  • Chrome extension simplifies the debugging process

And here goes a spoon of tar in a barrel of honey:

  • Sometimes the code needs to belong
  • You have to process data changes manually
  • It is view oriented

Making decision

Before making decision investigate the licensing issues, that may occur. As we said, both technologies are open source, however, there still may be some limitations connected with their usage.

Model-View-Controller pattern, that lets divide data of the project into tree category and modify each separately if it’s needed is an out-of-the-box feature of Angular 2. Which gives a huge advantage in comparison with React JS, that doesn’t have such option.

The other score one for Angular 2 is its ability to display templates writing easily. With this technology, you get very clear UI for the data and can get the end result with a really intuitive approach to the UI writing less code.

React JS is more complicated with it. The technology needs special functions to control data display. You have to determine the way data is represented before it’s coded into the DOM.

Data binding is another question. Angular 2 uses two-way data binding. The data is always directed only in one way, so you always know where your data changes. And this system gets really useful when it goes for debugging.

The Performance issues are extremely important when we work with very massive apps. Angular 2 has a watcher for every binding allows tracking all the progressions in Dom. One a View gets new updates, the system compares new values with primary meanings. And the problem is that the technology checks not only the meanings that changed but also all of them. This fact as you understand is a bane of Angular’s productivity.

React JS and its virtual DOM doesn’t need to check new data with the whole system. Once a user entered new data, React created a new virtual Dom and compares it with the previous one. And when the library compares and sees the difference between these two versions, the system rebuilds the virtual DOM. The procedure is performed with the server, thusly reducing the load on a browser. And while there are no active users on a site computer Technology Articles, React JS performance increases.
