Everywhere is talking about react native and react.js Now I want to know whether to work with react native must learn to react or react native of separate.
Thank you!
Yes, it is advised to learn React before you start with React Native, since the principles you'll need when developing in React Native are all based on React.
From Facebook:
React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React.
So before you study all the mobile specific API's and attention points, it's good to be familiar with React itself.
