React is a nifty tool when it comes to front-end web development. Compared with Angular, it possesses several benefits such as quick rendering, lesser development time, easier learning curve, and nuggets of Server-side Rendering. React is JS-centric that makes it far more straightforward, focused, and consistent than Angular.

Apart from the benefits mentioned above, Reactjs should be used over Angular because:

• Quick & efficient
• Suits well to Component-based UI
• Single Data Binding 
• Flexibility in building blocks
• Isomorphic JavaScript
• Large community support
• View & Controller at single place
• Helps to build large applications
