JavaScript Powers 98% of Websites: Choosing Between Vue js vs React vs Angular in 2025
JavaScript remains the backbone of modern web development, powering 98% of websites’ client-side functionality as of 2025. For developers, choosing the right framework is a critical decision that can significantly impact the success of a project. Three frameworks dominate the landscape: React, Vue.js, and Angular. Each has evolved over the past decade, offering unique strengths tailored to different use cases. This article dives deep into their performance benchmarks, cost analysis, and security features to help you make an informed decision.

Framework Performance Benchmarks in 2025
Performance is a key factor when selecting a framework. In 2025, advancements in web technologies have pushed the boundaries of what these frameworks can achieve. Using real-world data from PageSpeed Insights, Lighthouse, and JS Framework Benchmark, we compare React, Vue, and Angular across several performance metrics.
1. Load Time Comparison with Real Data Vue Js vs React vs Angular
Load time is critical for user experience and SEO. Here’s how the frameworks stack up:
- React: Leads with a First Contentful Paint (FCP) of 0.8 seconds and a Speed Index of 0.8 seconds. React’s Concurrent Mode and Server Components have reduced load times by 40%, making it ideal for applications requiring near-instant rendering.
- Angular: Follows closely with an FCP of 1.1 seconds and a Speed Index of 1.2 seconds. Angular’s Ahead-of-Time (AOT) compilation and Ivy renderer have significantly improved startup times.
- Vue: Slightly slower with an FCP of 1.2 seconds and a Speed Index of 1.7 seconds. However, Vue’s small bundle size (just 34.7KB gzipped) ensures efficient initial loads.
Bundle Size Impact:
- Vue: 34.7KB (smallest footprint)
- React + React DOM: 44.5KB
- Angular: 62.3KB
Smaller bundle sizes translate to faster load times, especially on slower networks. React’s Server Components further enhance performance by enabling server-side rendering for specific components, reducing the load on the client.
2. Memory Usage Analysis
Memory efficiency is crucial for applications handling large datasets or running on low-powered devices. Vue Js vs React vs Angular
- Vue: Excels in memory management, particularly with large arrays and data structures. Post-initial load, Vue uses the least memory.
- React: Matches Vue in runtime memory efficiency but requires slightly more memory during state updates.
- Angular: Consumes more memory, especially during state updates, due to its comprehensive feature set and dependency injection system.
Memory Usage Breakdown Vue Js vs React vs Angular:
- Ready Memory: Vue < React < Angular
- Run Memory: Vue ≈ React < Angular
- Update Memory: Vue < React < Angular
3. Runtime Performance Tests
Runtime performance measures how well a framework handles DOM manipulation, state management, and user interactions.
- React: Its Virtual DOM ensures efficient selective rendering, updating only the necessary parts of the UI. React’s Concurrent Mode and Server Components further enhance runtime performance.
- Vue: Leads in partial updates and DOM manipulation tasks. Vue’s Vapor Mode eliminates Virtual DOM overhead, boosting performance without requiring code changes.
- Angular: Improved significantly with incremental hydration and zoneless change detection, but still lags behind React and Vue in runtime efficiency.
Total Blocking Time (TBT):
- React and Vue: 0ms
- Angular: 200ms
This gap is particularly noticeable in applications with complex state management or frequent DOM updates.
Total Cost Analysis: Vue Js vs React vs Angular
The choice of framework has significant cost implications, including development time, maintenance, and scalability. Let’s break it down.
1. Development Time Requirements
Development speed directly impacts project costs.
- Vue.js: Ideal for small to medium-sized applications. Small apps take 2-3 months, while medium-sized apps require 4-6 months. Vue’s simplicity and intuitive API reduce the learning curve.
- React: Comparable to Vue in development time. MVPs take 2-3 months, and medium apps need 4-6 months. React’s flexibility allows for rapid prototyping but may require additional time for integrating third-party libraries.
- Angular: More time-intensive due to its complexity. Small apps take 3-4 months, and medium apps require 6-8 months. Teams often spend extra time mastering Angular’s features and TypeScript.
2. Maintenance Costs Vue Js vs React vs Angular
Maintenance typically accounts for 15-20% of the initial development cost annually. For example, a $100,000 application may cost $15,000-$20,000/year to maintain.
- Angular: Provides a structured maintenance path with detailed update guides and migration tools. However, frequent version updates demand ongoing attention and resources.
- React: Maintenance is simpler due to its backward compatibility and minimal breaking changes. However, reliance on third-party libraries can increase long-term costs.
- Vue: Allows targeted updates to specific components, reducing the risk of breaking changes. This approach keeps maintenance costs predictable and manageable.
Factors Influencing Maintenance Costs:
- Documentation Quality: Well-documented frameworks reduce long-term costs.
- Code Complexity: Unnecessary features can increase testing and debugging efforts.
- Update Frequency: Frequent updates may require additional developer training.
Security Features Comparison
Security is a top priority for modern web applications. Here’s how the frameworks compare:
1. React
- Strengths: React’s JSX syntax inherently protects against XSS (Cross-Site Scripting) attacks by escaping embedded expressions. Its ecosystem includes robust libraries like React Helmet for securing headers and React Router for safe navigation.
- Weaknesses: Reliance on third-party libraries can introduce vulnerabilities if not properly vetted.
2. Vue
- Strengths: Vue’s template-based syntax automatically escapes HTML, reducing XSS risks. The framework also supports Content Security Policy (CSP) and provides built-in safeguards against common vulnerabilities.
- Weaknesses: Smaller ecosystem compared to React and Angular, which may limit access to specialized security tools.
3. Angular
- Strengths: Angular’s built-in security features are among the most comprehensive. It includes XSS protection, sanitization APIs, and HTTP client safeguards. Angular also enforces TypeScript, reducing runtime errors and vulnerabilities.
- Weaknesses: The steep learning curve can lead to misconfigurations, potentially introducing security gaps.
Security Best Practices:
- Regularly update dependencies to patch vulnerabilities.
- Use linting tools and static code analysis to identify potential security issues.
- Implement authentication and authorization mechanisms tailored to your framework.
Conclusion: Which Framework Should You Choose?
The choice between React, Vue, and Angular depends on your project requirements:
- React: Best for dynamic, high-performance applications with complex state management. Its ecosystem and flexibility make it a top choice for large-scale projects.
- Vue: Ideal for small to medium-sized applications where simplicity and speed are priorities. Vue’s lightweight nature and ease of use make it a favorite among startups and solo developers.
- Angular: Suited for enterprise-level applications requiring a full-featured framework with built-in tools and strong TypeScript support.
By considering performance benchmarks, cost implications, and security features, you can select the framework that aligns with your project goals and team expertise. In 2025, all three frameworks continue to evolve, ensuring that developers have powerful tools to build the next generation of web applications.
