Absolutely, this React is built with a core focus on beginners. If you have even a basic understanding of HTML, CSS, and JavaScript, you are ready to start learning React.

React builds on top of JavaScript, so you will need some JavaScript basics first. But once you understand the fundamentals, React actually makes building user interfaces simpler and more organized.

The fastest way to learn ReactJS is through structured, hands-on practice. With uCertify’s hands-on labs you can practice your way through the course for effective learning. 

It depends on your pace, but most learners can grasp the React fundamentals in a few weeks with consistent effort.  If you are consistent with the number of hours you are putting in every week, you can learn ReactJS.
