“Hey guys, In this section we are going to go through the 3 aspects of React.js i.e. class based components, handling user events and exporting components, During 2 previous courses we have introduced the general concept of React.js, difference between using React and Angular.js, what are react components and as well as we have introduced a little bit what is Virtual DOM and how it works. We’ve gone little bit further and investigated what are react components elements and instances, how to declare a button, how to create, update, and destroy child elements and talked a little bit about the use of RxJS with React.”
