Welcome to this course: The Ultimate ReactJS Developer Course. React is a JavaScript library that communicates changes on a User Interface to the browsers quickly, without having to re-render anything except the part of the display that needs to change. Building web applications with maintainable and performant user interfaces is a challenge that many have faced for more than a decade, but no one has risen to this challenge quite like ReactJS. Many new users recognize the benefits of Reactjs and adopt it in their own projects, forming a fast-growing community. The speed at which Reactjs has evolved promises a bright future for those who invest in learning it today.

In this course, you'll learn:

• Test your React components with Jest test framework

• Use JSX to speed up your Reactjs development process

• Create React elements with properties and children

• Get started with stateless and stateful React components

• Add reactivity to your React components with lifecycle methods

• Utilize the Flux application architecture with your React components

• Integrate your React components with other JavaScript libraries

• Share data between various React components and techniques for data flow within a React app

• Handle user interactions with the help of event handlers and dynamic components

At the end of this course, you will not only have a good understanding of ReactJS but will also have built your very own responsive frontend applications from scratch.
