ReactJs Introduction

React is an efficient, declarative, and flexible JavaScript-based UI development library. Facebook and an open-source developer community run it and It was created by Jordan Walke, who was a software engineer at Facebook.

Although React is a library rather than a language, it is widely used in web development, and today, most of the websites are built using MVC (model view controller) architecture. In the MVC(Model View Controller) architecture. React is the ‘V’ and “v stands for view. Whereas the MVC architecture is provided by the React-Redux or Flux. This library was first released to the public in the month of MAY 2013 and is now one of the most commonly used frontend libraries for web development.

React offers different types of extensions for overall application architectural support, such as Flux and React Native, beyond mere UI and then we combine it into a higher-level component, i.e., the form component itself.

Why learn ReactJS?

React is popular today has eclipsed that of all other front-end development frameworks(like angular, node). Here is why:

Creation of dynamic applications: React create dynamic web applications because it requires was less coding part and offers more functionality, as opposed to JavaScript. Where coding often gets complex very easily and quickly.

Improved performance: React js uses Virtual Document Object Model (DOM), thereby creating web applications faster. Virtual DOM compares the components’ previous(last) states and updates(new) only the items in the Real DOM that were changed. Instead of updating overall components again, as conventional web applications do.

Reusable components: The React components are the building blocks of any React application. The single app usually consisted of multiple components. These react components have their logic and controls. It can be reused throughout the overall web application. Dramatically reduces the web application’s development time.

Unidirectional data flow: React js is a unidirectional data flow. When designing a React app(web development app), developers often nest child components within parent components. The react data flow in a one (single)direction. It becomes easier to debug errors and you know where a problem occurs in a web application at the moment in question.

Small learning curve: React is easy to learn. it was mostly combined basic HTML and JavaScript concepts with some beneficial additions.

React tools for easy debugging: Facebook has released a Chrome extension and that can be used to debug React applications. Easy and quickly debugging React web applications faster and easier.
