"Angular is a Javascript-based framework, whereas React JS is a JSX-based Javascript Library. Angular JS is typically used to create complex enterprise-grade applications like progressive websites or single-page applications. At the same time, React is used while creating interactive UI elements in applications with different regular data. Angular has a steeper learning curve because of its more significant number of in-built features. Meanwhile, React has comparatively smaller packages to learn.

These are some basic distinctions that help one to understand the fundamental difference between Angular and ReactJS."
