Weaknesses:

• Steep Learning Curve: Complex concepts and steep learning curve
• Verbose: More boilerplate code compared to React/Vue
• Performance: Generally slower than React/Vue for simple apps
• Opinionated: Less flexibility in architectural choices
• Bundle Size: Larger bundle sizes compared to alternatives

Performance Comparison

Performance is crucial for user experience and SEO. Here's how the frameworks compare:

Rendering Performance:

• React: Virtual DOM provides efficient updates, excellent for dynamic content
• Vue: Fine-grained reactivity system, minimal DOM manipulation
• Angular: Change detection with zones, can be optimized but generally slower

Bundle Size:

• React: ~42KB (runtime) + additional libraries
• Vue: ~34KB (runtime) - smallest of the three
• Angular: ~129KB (core) - largest but includes everything

Memory Usage:

• React: Moderate memory usage with efficient virtual DOM
• Vue: Lowest memory usage due to optimized reactivity
• Angular: Higher memory usage due to dependency injection and zones

Learning Curve and Documentation

The time required to become productive varies significantly between frameworks:

Beginner Friendliness:

• Vue: Easiest for beginners - HTML-like templates and gradual adoption
• React: Moderate difficulty - JSX and functional concepts
• Angular: Most difficult - TypeScript, RxJS, and complex concepts

Time to Productivity:

• Vue: 2-4 weeks to become productive
• React: 4-8 weeks to become productive
• Angular: 8-12 weeks to become productive

Documentation Quality:

• Vue: Best documentation - comprehensive and beginner-friendly
• React: Good documentation but fragmented across libraries
• Angular: Comprehensive but complex documentation

Ecosystem and Community

A strong ecosystem and community support are crucial for long-term success:

Community Size:

• React: Largest community - 22M+ GitHub stars, 200K+ npm packages
• Vue: Growing community - 206K+ GitHub stars, 30K+ npm packages
• Angular: Strong enterprise community - 93K+ GitHub stars, 25K+ npm packages

Third-Party Libraries:

• React: Extensive ecosystem for every need
