Now a days lots of JavaScript libraries and frameworks are available in the market. But here we will talk about most popular component-based JavaScript front-end libraries that is ReactJS created by Jordan Walke, a Facebook engineer and there is a large community working hard in order to make React better in every release. React is a component based library which is used to develop interactive User Interfaces. The main purpose of React is to be work as fast, scalable, and simplicity. React allows developers to create single page applications or large web applications which can change data, without reloading the page.
Why should we use ReactJS and its feature?
When we create React app then it generally made up of two parts, components and HTML, components: that contains your HTML code in the form of pieces that your user will see. And the HTML doc where all separate created component will render. It’s easy to learn and understand when we have basic programming knowledge of JS, HTML and CSS. So ReactJS is very simple to learn. We can build professional web and mobile applications with well-defined lifecycle, component-based approach and use of JavaScript, HTML, JSX. We can create mobile applications with the approach of React Native.
React uses JSX and Virtual DOM. Instead of using regular JavaScript react uses JSX. JSX is JavaScript XML. It’s an XML/HTML and uses these tags to render all components.
Virtual DOM uses a node tree similar to actual DOM that lists their attributes and the elements as objects and their properties.
Finally the use of react JSX is easy to code which makes the application very simple and understandable. More you can reach and learn ReactJS from their official site.
