The user interface is the layer which acts as a medium for interaction between the user and the software. Only when the user interface is interacting and engaging, the website would be interesting for its online visitors.
Easy to use
Using React is very simple in order to develop interactive UI’s that are interesting and appear nice. It also has the added advantage of updating and rendering its own components placed in it accordingly as per the changes made with time. React makes us of declarative views that make code more organized and thereby making it easier for us to debug.
Made up of components
React is all about ‘learning once and then writing anywhere’ concept. New features can be developed using React instead of replacing the old and existing code which is redundant. It uses Node to render on the server and uses React Native to render on the mobile applications.
Render () method
All the components of React use the render () method which is used to take in input streams of data and returns what to display on the screen as output. this.props can be used to access the input data that is passed into the component.
Internal state data
Along with this.props which is used to take the input data, there is another component present that can maintain the internal state data too! When the associated state changes, the markup will be re-updated by re-invoking render ().
A Todo application can be built by using ‘props’ and ‘state’. In this case, ‘state’ is used to maintain a record on all the input text that the user has given. It appears like the event handlers are invoked and rendered inline, in a single statement but it is not so! It is implemented only via event delegation.
That’s all you need to know about React!
