What is React?

React is an open-source JavaScript front-end library developed by Facebook for building interactive user interfaces and web application front-ends. Released in 2013, React aims to simplify the development of complex, changing data flows in web UIs.

React builds on basic HTML/CSS/JS to provide a declarative component model. In this model, UIs are broken into encapsulated, reusable pieces called components. These work similarly to Lego blocks snapping together to form complex UIs.

Components use a templating language called JSX that resembles HTML to render content, can have a local state, and update dynamically in response to data changes. Events triggered from one component bubble up to notify parent components automatically through a unidirectional data flow paradigm.

Virtual DOM tracking of changes combined with selectively re-rendering only components that change enables very high performance compared to raw JavaScript ops. React can thus power data-intensive apps like Facebook and Instagram that show constantly updating content flows.

React promotes loose coupling between components and thinking regarding simple, reusable interfaces over concrete implementations. Components also have lifecycle methods like componentDidMount(). Additional libraries like React manage routing in single-page apps.

Pros and Cons of Using React

Pros

• Promotes reusability via encapsulated components
• Components offer separation of concerns
• Virtual DOM provides excellent performance gains
• Unidirectional data flow simplifies data handling logic
• The large open-source ecosystem of reusable React component libraries
• Easy integration into existing codebases
• The growing developer community provides abundant support resources

Cons

• Only handles the view layer, not a complete framework
• Many auxiliary libraries are needed for complex apps (routing, state management)
• Code complexity from JSX and nested component trees
• Steep learning curve mastering inner workings like state and lifecycle
• Rapid evolution means breaking API changes, which is not uncommon
• Less out-of-box project scaffolding sets up

Key Differences Between Flutter, Angular, and React Native

Flutter, Angular, and React Native have some major differences when it comes to technology, performance, ease of use, and approach:

Tech Stack

• Flutter uses the Dart programming language and provides its robust widget set for building mobile interfaces. This allows it to compile code into native machine code for excellent performance.
• Angular utilizes TypeScript, a typed superset of JavaScript and HTML and CSS, for building responsive web applications. It compiles down to plain JavaScript code to run in browsers.
• React Native is based on the React JavaScript library and uses the same paradigm of components. It compiles code to native UI components while communicating with native code through a JavaScript bridge.

Learning Curve

• Flutter offers a moderately easy learning curve for developers with prior experience in object-oriented code and mobile development. Its declarative widget-based approach is intuitive.
• Given the complexity of its technology stack, Angular has a rather steep learning curve, including TypeScript, components, directives, services, dependency injection, and hierarchical injectors.
