ReactJS Tutorial

ReactJS is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies. ReactJS was one of the first JavaScript-connected projects released as open source by Facebook.

React can be used as a base in the development of single-page or mobile applications. Complex React applications usually require the use of additional libraries for state management, routing, and interaction with an API. ReactJS uses JavaScript to create components through JSX. JSX is a language that looks like HTML, but ultimately compiles down to JavaScript statements.

React allows developers to create large web applications which can change data, without reloading the page. The main purpose of React is to be fast, scalable, and simple. It works only on user interfaces in application. This corresponds to view in the MVC template. It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC. ReactJS allows for direct work with components and uses downward data binding to ensure that changes of child structures don’t affect their parents. That makes code stable.

There are so many open-source platforms for making the front-end web application development easier, like Angular. ReactJS is very very simpler to build a professional website and mobile applications. ReactJS is very easy to learn. Anyone with a basic previous knowledge in programming can easily understand ReactJS. One of the most important use of ReactJS is reusability. That means it will support the code reusability extensively. So at the same time we can make IOS, Android and Web application.

Virtual DOM is one of the best feature of Reactjs. React creates its own virtual DOM where your components actually live. This approach gives you gains in performance because React calculates what changes need to be made in the DOM beforehand and updates the DOM tree accordingly. Browsers are slow and the DOM API is hard to deal with. You can see Virtual DOM as a fake browser that is much faster. React’s fake browser acts like an agent between you and the real browser.
