What are alternatives to querySelector?

Native DOM traversal : firstElementChild, lastElementChild, children, nextElementSibling, parentElement. Chain them for strong access.

Is querySelector slow or bad?

Not always slow, but brittle—ties JS to CSS strings. Breaks on markup changes, hard to refactor.

How do I start ditching querySelector today?

Map your DOM tree post-load using functions like getDomObjects(). Centralize refs, traverse structurally.
