Best Features in React JS

 

aTeamIndia utilises some of the best features of React JS for their development services.

  • Declarative

React is known to produce user interfaces that are interactive for both websites as well as mobile applications. All you have to do is make simple views for each state and React can automatically upload and render as and when the data witnesses a change.

  • Virtual DOM

Every DOM will have a respective virtual DOM object. This is a defining feature of React. This feature produces a copy in the virtual platform of the original DOM. This is easier as a virtual DOM can be updated in less time as compared to original DOM.

  • Event handling

Another great feature of React is that it can produce an even system on its own which is also compatible with the W3C model of object. When there is a native event, this feature provides a cross browser interface. This means that the event names and fields will now be compatible. It also has a mechanism to reduce big loads of memory.

  • JSX
    JSX is another popular feature of React JS. It slightly resembles HTML. However, it is actually a combination of JavaScript and XML. These are the building blocks of React user interface. This feature makes it easier for developers to write React components. Web developers find this to be one of the best features of React as it reduces their workload.
  • Performance
    React has a feature called flux controls that employ a one way data binding system. This will automatically update what the users view and will also regulate the workflow of the application. The above mentioned virtual DOM function compares the new and old data and adds the update to the view as well.
  • React Native

React Native is a custom renderer which uses components that are Native rather than React for building the framework. All the developers have to do is to be well-versed in some basic concepts like JSX, React Native etc. React Native also gives access to many other features.

  • Component Based

In order to make a user interface, the web page and its contents are divided into components. Thus, making it component based. This component is a self containing module that will store all the visual aspects of the application. Rather than in templates, the components are written with the help of JavaScript. This enables you to send data across the application.

React JS keeps evolving by incorporating techniques and features that have never been experimented within the process of web application development. These best features of React make the best use of immutable resources. An application can be made with a better performance layer with the help of these features. React.js feature component also enables you to come up with new features without having to rewrite everything else. Since it is individually separated, it does not affect the rest of the application. aTeamIndia has been using React since its inception and has taken these features to the best of their needs.

What’s New with React 16?

 

React 16.0 probably had the most anticipated release. Many new features have been added and improvements have been made. React as we all know is a JavaScript library which is used for the purpose of creating user interfaces. It is being maintained by Facebook and also by individual developers and companies simultaneously. It is known to be able to fetch rapidly changing data. This makes it suitable for developing UI from single page websites to complete mobile applications. The newest version, React 16, has a new core structure as its base which is new to React. This is known as the fiber. The fiber facilitates the new features like better error handling, async rendering etc.

A look at the following features will let us understand the difference between the old and new version and the improvements made.

  • An array of elements can now be returned with the help of a component’s render method. All you have to do to prevent key warning is to add a key to an element. This is same with all arrays. Previously, any kind of runtime errors would have broken React and lead to a cryptic error message which will then require you to refresh the page. However, React 16 has a much better way to handle these errors. If at all an error happens, the entire component will be uprooted. This will make sure that corrupted data is not displayed.
  • React 16 also has the provision of error boundaries. A complete unmounting of the component might affect user interface so error boundary is a good alternative. The error boundaries can detect the errors even before it gets to the display. It will display a UI that you can fall back on. This helps you to get a smooth user interface and is a much safer option.
  • It has also introduced portals. If a DOM node exists outside the hierarchy of a parent component then portals help with rendering the children component into the parent ones.
  • There is a huge size difference. This is due to the changed packaging. This does away with process.env checks which make it slow especially in Node.
  • React 16 also has introduced a completely new server renderer. It is entirely rewritten. This rewritten version is faster. Because it supports streaming, bytes can be sent in a much faster rate. It includes a completely rewritten server renderer. A bundle React is not needed for better rendering performance.
  • React 16 can also hydrate the server rendered HTML better upon the clients receival. The initial render and the result from the server need not match completely.

All the leading websites are now using React 16.0 and aTeamIndia is the most trusted developer when it comes to React. They have years of experience in React and are well versed with the newest version. They have a team that is updated with all the new updates and latest changes. They also have the experience of working with the latest technologies like React Native and Angular.
