- AJAX support differed
- CSS property behavior was inconsistent
- DOM traversal APIs behaved unpredictably
jQuery internally normalized these inconsistencies.
Examples:
- Event normalization
- Unified AJAX transport
- Cross-browser selector handling
- Consistent animation APIs
- CSS property abstraction
Internally, jQuery often used browser feature detection instead of browser sniffing.…
