To understand the React Native vs. React.js difference better, you need to understand the difference between a framework and a library.

Framework vs. Library:
​

A React.js library is a collection of predefined or pre-composed rules and routines that a developer can use multiple times without writing every line of code from scratch. Libraries cover common use cases, and one can incorporate them into frameworks.

On the other hand, frameworks are more intricate than libraries. Built as a framework, React Native has pre-built components and reusable code that supports the developers while building mobile apps.


Now, a common question arises: is React Native harder than React.js? You can learn both as they follow similar principles or methodologies. However, learning React Native is much easier if you already know JavaScript or even faster if you know React.js.
