Both Angular and React are well-known JavaScript front-end frameworks, although their architecture and design patterns vary. Angular is a comprehensive framework that comes with everything required to create intricate, large-scale apps. The architecture is component-based, and templates, logic, and styles are all defined in the same file.
React, on the other hand, is a library that specializes in creating UI components and depends on outside libraries for extra capabilities. It follows a unidirectional data flow approach and makes use of a virtual DOM. Additionally, React encourages developers to design reusable, composable code and supports the usage of functional programming techniques.
