What is React and what are the features of React
Features Of ReactJS
A ReactJS application is known to be a multi-component application. Each component of the ReactJS application is reusable and is responsible for outputting a small, reusable piece of HTML code. Being the heart of all React applications, its components can also be nested. This nesting with other components allows the creation of complex applications built of simple building blocks.
One-way Data Binding:
ReactJS follows unidirectional data flow also known as one-way data binding, which certainly gives better control to the user throughout the application. But it requires additional features, in case the data flow is in another direction. This also increases the efficiency of the application by making it more flexible.
To fill data in HTML DOM, ReactJS uses virtual DOM based mechanism as it works fast. The virtual DOM only changes individual DOM elements. Thus it does not reload complete DOM every time and is certainly fast.
ReactJS uses JSX file. This makes the application simple and easy-to-understand. Again the reusable codes make it more simple to use and learn.
ReactJS is a great performer as it manages a virtual DOM. The DOM deals with HTML, XML or XHTML. It is a cross-platform and programming API. With ReactJS, the user did not write directly to the DOM, but to the virtual DOM thus leading to smoother and faster performance.
