Angular is a complete front-end framework that uses TypeScript, a superset of JavaScript, as its programming language. TypeScript adds features like type-checking and interfaces to JavaScript, making it more robust and scalable. React, on the other hand, is a JavaScript library that is focused on building user interfaces. React uses JSX, which is a syntax extension for JavaScript that allows developers to write HTML-like syntax within their JavaScript code.

Angular provides two-way data binding, which means that changes in the model are reflected in the view, and vice versa. This makes it easier for developers to manage data in their applications. React, on the other hand, uses one-way data binding, resulting in changes in the model only being reflected in the view and not vice versa.

Angular is a complete framework that provides a clear architecture for building web applications. It uses a component-based architecture, where the entire application is broken down into small, reusable components. React, on the other hand, is a library that only focuses on the view layer of an application. This means that React doesn’t provide a clear architecture for building an entire application, and developers need to use additional libraries and tools to build a complete application.

React is known for its high performance, especially when it comes to rendering large lists or complex user interfaces. This is because React uses a virtual DOM, which allows it to update the user interface efficiently without requiring a page refresh. Conversely, Angular can be slower when it comes to rendering large lists or complex user interfaces, especially when compared to React.

Both Angular and React have large and active communities, with a vast ecosystem of libraries and tools. However, React’s community is generally considered to be larger and more active than Angular’s. Additionally, React has a higher adoption rate among developers, which means that there are more job opportunities for React developers.
