ReactJS Features | React Tutorial
Nowadays, ReactJS gaining quick popularity as the best JavaScript framework among web developers. It is playing an essential role in front-end development. The important features of ReactJS are as following.
- JSX
- Components
- One-way Data Binding
- Virtual DOM
- Simplicity
- Performance
1. JSX
JSX is a JavaScript syntax extension. It stands for JavaScript XML. It's an XML or HTML like syntax. This syntax is processed into JavaScript calls under React Framework. JSX extends the ES6 so that HTML like text can co-exist in JS react code. It is not necessary, but it is recommended to use JSX in ReactJS.
2. Components
Components are an important feature of ReactJS, all about components. This application is made up of multiple components, and each component has its own controls and logic. These components are reusable which helps us to maintain the code when working on larger scale projects.
3.One-way Data Binding
ReactJS follows unidirectional data flow i.e one-way data binding. unidirectional data flow gives us better control throughout the application. If the data flow is in another direction, It requires additional features. It is because components are supposed to be immutable, i.e the data within them cannot be changed. Flux is a pattern that helps us to keep our data unidirectional. This makes the application more flexible and leads to increase efficiency.
4. Virtual DOM
A virtual DOM object is one kind of representation of the original DOM object. that's works as a one-way data binding. The entire UI is re-rendered in virtual DOM representation, Whenever any modifications happen in the web application, . Then it checks the difference between the new DOM and the previous DOM representation. Once it has done, only the things that have actually changed will update by the real DOM. This makes the application faster. There is also no wastage of memory.
5. Simplicity
ReactJS uses JSX files which makes the application simple to code as well as understandable. We know that ReactJS is a component-based approach that makes the code as reusable as our need. This makes it simple to learn and use.
6. Performance
ReactJS is a great performer. This feature makes it much better than any other frameworks out there today. Because it manages a virtual DOM. The DOM is a cross-platform and programming API that deals with XML, HTML, or XHTML. It exists entirely in memory. So whenever we create a component, we did not write directly to the DOM. we are writing virtual components that will turn into the DOM leading to faster and smoother performance
