React JS or React is an open-source javascript library that is used for constructing single-page applications. It is essential while you are handling the view layer of mobile and web apps. Through react, you can also construct reusable UI components. reactJS was first discovered by Jordan Walke. Jordan Walke a software engineer on Facebook was the creator of reactJS.

If you are a web developer who is looking to create a reusable webpage that can change data without reloading the webpage, react is crucial for you. The main motive of reactJS is to make tasks scalable, fast, and most importantly simple. reactJS works on the user interface of the application that corresponds to the view in the MVC template. It allows you to combine it with other frameworks and JavaScript.

The React JS course syllabus starts from basics such as JSX and React components, state, props, etc. After completing these, we will cover more advanced concepts such as passing data between components and components composition, unit testing, styling and more valuable utilities.

React is a JavaScript library that is used to construct streamlined and responsive user interfaces for mobile and web applications. For composing complex UIs from isolated and small pieces of code using React is one o the best options that you have got. It will let you write applications that run in different environments, behave consistently, and is easy to deploy and test.

The React JS certification training is designed to provide you the knowledge and skills required to become a successful web and mobile application developer. It starts with the fundamental concepts of React and its architecture. The React online training then focuses on Redux and its features, demonstrates how React and Redux can be used together to build extensive web applications and later guides you on how to develop responsive UIs to handle user interactions in a mobile environment using React Native.

On completion of the React training, learner will be able to:
Develop a proper understanding of Web Development Architecture
Create application using React components
Perform Navigation using Routes
Build Web Applications using React with Redux
Program Async Actions using Redux-Saga Middleware
Write Queries using GraphQL
Execute Test Cases using Jest
Deploy Applications using Docker and Nginx
