- Ideal for learning and mastering core concepts of Javascript.
🔴 Cons:
- Could be time-consuming for complex UIs.
- Can’t use reusable components.
- DOM is manipulated manually.
- Code complexity increases in large-scale apps.
⚛️ What is ReactJS?
A well-known JavaScript toolkit called ReactJS was developed by Facebook to help design interactive user interfaces and single-page applications (SPAs). In 2025, its component-based architecture will make it perfect for scalable frontend development.
🟢 Pros of ReactJS in 2025:
- Faster development using reusable components.
- Performance of website is boosted due to the presence of Virtual DOM.
- Have a larger community support and ecosystem.
- APIs can be integrated easily along with backend, and third-party libraries.
- Suitable for large-scale applications and startups.
