Framework

A framework is a comprehensive platform that provides structure, tools, and conventions for building web applications. Unlike libraries, frameworks dictate the architecture and flow of your application.

Popular Frontend Frameworks

React Component-based library (technically) for building user interfaces.

Vue Progressive framework with gentle learning curve and excellent documentation.

Angular Full-featured framework with TypeScript, dependency injection, and comprehensive tooling.

Svelte Compiler-based framework that generates highly optimized vanilla JavaScript.

Framework vs Library

Framework

• Provides complete application structure
• "Inversion of control" - framework calls your code
• More opinionated

Library

• Provides specific functionality
• You call the library's code
• More flexible

Benefits

• Faster development with pre-built solutions
• Best practices and patterns built-in
• Active communities and ecosystems
• Consistent code structure across teams

Considerations

• Learning curve
• Bundle size
• Performance overhead
• Lock-in to framework ecosystem
