Pros and cons
What jQuery does especially well — and the limits to anticipate.
Pros
- Simple, intuitive syntax for DOM manipulation
- Huge installed base and available resources
- Small and lightweight for small projects
- Excellent old browser compatibility
Cons
- Maintenance mode — no new features
- Not suited for complex applications
- Declarative DOM approach less modern
jQuery: when it makes sense.
jQuery remains useful for legacy maintenance and small projects; for new apps, prefer React, Vue, or Angular.
Keep if
You maintain legacy code using jQuery.. You build a simple app without modern frameworks.
Challenge if
You're starting a new modern web project.. You're building a SPA (Single Page Application).
