Answer
jQuery simplifies cross-browser DOM selection compared to querySelector and getElementById.
Quick Answer
jQuery selectors use the Sizzle engine and have extra pseudo-selectors (:animated, :visible, :checkbox). Vanilla JS querySelector/querySelectorAll are natively optimized and faster - no wrapper object creation overhead. For modern code, vanilla selectors are preferred; jQuery selectors still offer convenience pseudo-selectors and always return a jQuery object (never null).
