JavaScript DOM Manipulation: 6 Patterns That Replace jQuery
You're still reaching for jQuery — or 200 lines of vanilla — to do things the browser now does in one line.
6 modern DOM patterns: querySelector + closest, classList, DocumentFragment, replaceChildren, event delegation, and AbortController.
Vanilla JavaScript · zero dependencies · Baseline in every major browser · 2026.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The 6 patterns (one per minute):
· #3 DocumentFragment — batch 1000 inserts into ONE reflow instead of 1000 (the perf win, shown live)
· #1 querySelector + querySelectorAll — one API, any CSS selector; static NodeList vs live HTMLCollection; closest() instead of parentNode chains
· #2 classList — add / remove / toggle (with the boolean force-arg) instead of the className += ' x' whitespace bug
· #4 replaceChildren — why innerHTML kills listeners and opens an onerror XSS hole, and how nodes-or-strings fixes it
· #5 Event delegation — one listener on the parent + event.target.closest, works for items added later
· #6 AbortController — pass one signal to every addEventListener, then controller.abort() removes them all
Plus the honest part: when innerHTML, className =, and manual removeEventListener are still totally fine.
